and Ayman from Egypt
This was another interesting chat with several students dropping in at one time or another. The main question to emerge from this chat was: How does a circuit breaker work? We know it detects electricity surges and at a dangerous point, trips a switch and sends the excess into the ground. But what is the physical condition that causes the switch to change positions? How does it work exactly? If you know the answer, tell us. And the bonus question is, Is there any difference between a resistor and a capacitor, and if so, what’s the difference? One strange thing about our chat was that every time we would talk about circuit breakers, HearMe would overload and we would all be bumped from the program. We had to keep going back again and again. The last time it went out, Marina was telling us about her email school projects. You’ll have to continue in email to the eclass, Marina.

John: Hello, Ying.
John: Ayman is in Italy.
Vance: http://www.homestead.com/vstevens/files/efi/ayman.htm
Ying: Oh, I see. [Vance has just introduced Ayman via his web page - gvs]
Michael: Hello Ying. How are you?
John: Always nice to see you, Ying. How are you?
Vance: http://www.homestead.com/vstevens/files/efi/students.htm [Vance introduces Ayman to everyone else present - gvs]
Ying has left
Michael: I remember now Ayman. I read your post when you first joined webheads.
Vance: Yep, and it's on the webheads site
Ying has joined
Vance: http://www.homestead.com/vstevens/files/efi/students.htm
John: Do you have graphics turned on? [We're trying to figure out why Ayman can't read our text messages - gvs]
Maggi: Hi Ying
John: Welcome back, Ying.
Ying has left
Ying has joined
John: Ying, are you having problems with your connection?
Ayman has left
Ying: Bad connection!!
Michael: Yes - a joke!
John: Bad connections are terrible. I have one sometimes.
[Maggi tells us all a joke. It goes something like this. Two women are talking. One asks the other, "Is that a suppository in your ear? The other one says, "Oh, yes, I suppose it is. Well, now I know what happened to my hearing aid." - gvs]
Vance: a suppository !!!
John: Very funny.
John: Is that where she hears things?
Ying: Sorry,,, I don't understand maggi's joke.
John: I have to remember that for my students.
Ying: why?
Ying: It seems a funny joke.
[Now Maggi is in the position of having to explain what a suppository is. - gvs]
John: Or, if they have a fever or something. It's something you put into your bottom hole.
Ying: But I can not hear maggi's joke because connection problem.
Maggi: two old women were having breakfast in a restaurant
Maggi: Mabel said to Ethyl, I think you have a suppository in your ear.
Vance: Oh, Ying Lan, I just asked if you could hear us ...
Ying has left
Ying has joined
Maggi: Ethyl takes it out and says now I have an idea where my hearing aid is...
Ying: Yes, I can.
Ying: But the connection is bad.
Michael: So Ethyl was trying to unblock her ear with a suppository?
Vance: hello
Michael: Ok ..now I get it.
Michael: I'm a bit slow....
Michael: (smiles)
Ying has left
Ayman has joined
Michael: lol
John: Ying has been having a lot of connection problems today.
Vance: what?
Vance: turn the volume down
Michael: lol
Ying has joined
Vance: The computer (what?)
Michael: Sorry Ayman - we can't hear you now....that's better.
John: Poor connections
Ying has left
Vance: The power went off
Vance: right?
Vance: a fuse? [Ayman is explaining to us in voice chat what happened with his connection; apparently he blew a fuse or circuit breaker in his flat. - gvs]
Vance: Were you using too much power, so you had to reset the fuse?
[Vance is being corrected here. It probably wasn't a fuse, but a circuit breaker. Vance wants to know, how does a circuit breaker work? - gvs]
John: You go first, Michael
Vance: a circuit breaker
John: A fuse burns out, a circuit breaker doesnt. The word fuse comes from the fact that it fuses.
Vance: ok
Ying has joined
Vance: actually, i think I knew that :-)
John: Vance, I just discovered it, myself.
Ying has left
Ying has joined
John: No, I meant about why the fuse is called a fuse.
John: So, tell us, then.
John: But, it doesn't burn out. Why does it turn off?
Ying has left
John: Sounds logical (but then, so do politicians). I still don't know how they work.
Ying has joined
Ying: <Type here to chat>
Ying: It is windy.
Ying: I feel a little cold here.
Ying: I don't know the actual temperature here.
Michael: 27C = 81F
John: 30C = 86F
Ying: I hate this bad connection problem.
John: I know how you feel, I always hate it when I have such a connection.
Michael: Yeh it's bad luck Ying.
John: Puerto Rico is rather strange in this, we use both quarts and liters, miles and kilimeters, etc.
Ying: Why do you want to talk about measure unit?
Michael: Pots, midis, schooners, ponies, glasses....of beer
Ying: I am stupied about math...
Michael: Me too Ying.
John: We got onto this topic because I wasn't sure about my temperature in Celcius.
Maggi: ans you work in a bank? LOL
Michael: I failed in school.
Ying: Yeap././.
Michael: LOL
Ying: I hate Number.. but I love money.
John: I used to get "P" in Math (P is Pass for non-academic reasons).
John: So do I, Ying.
Ayman has left
Ayman has joined
John: See you, then, Michael.
Ying: Michael. do you want to go?
Michael: You know that too???
Michael: LOL
John: Who else, Maggi?
Michael: Ahhhhhhhhgggggg!
John: You mean, like Ush?
[Here, we're wondering what's the difference between a resistor and a capacitor. Then we start joking about the verb from resistor, to resist. Why isn't there a corresponding negative verb, irresist? - gvs]
Michael: I can't irresist you!
Vance: I can irresist you
Michael: Ying and Ayman - irresist is NOT a word. (I was joking.)
Vance: We're getting a little crazy here
Vance: I can't resist you
Michael: Bye!!!
Michael has left
Moral has joined [Now that Moral is here, we start talking in text chat more than voice - gvs]
Maggi: Hi Moral...
John: Hello, Moral. How are you today?
Moral: Hi there!
Moral: I worked today John.
John: Today is my day, off, but I still have to work.
Ying has left
Maggi: when do you have time off then?
Ying has joined
Vance: Hi Moral
Moral: Hi Vance.
John: I don't have time off.
Vance: Can you hear us today?
Moral: It is my day off too. But I have to work over time today.
Moral: No Vance.
Maggi: I meant Moral...teachers never have time off...:-)
John: When I don't have to go to work, I still have to correct papers.
Moral: Yes Maggi, eapecially webheads teachers.
Ying has left
Moral: especially...
Maggi: that is one reason why I don't give homework John
Vance: Moral, maybe you can help me ...
Maggi: except online
Moral: I 'd be happy to Vance, but how?
John: Unfortunately, since I teach writing, I have to give a lot of written homework.
Moral: Where is Michael?
Moral: I see he is online.
Moral: John, do you have voice today?
Vance: Do you know how a circuit breaker works? (You just missed Michael)
John: Yes, I got myself a new microphone and earphone setup.
Vance: I just asked if Moral could hear
Moral: Yes, Vance. I think so. When the current reaches a value, it breaks the circuit.
Vance: And how does it do that. It "trips" the switch. What causes the switch to move?
Moral: mostly, temperature.
Maggi: the writing assignments are online John
Vance: vstevens@emirates.net.ae
John: But, they are still writing assignments.
John: Does anybody know if Ayman has text turned on.
Maggi: oh yes...just not on paper...but the quality has improved tremendously
Moral: Vance, a resistance is in it. When current is high, the resistance turns hot and trip the switch.
John: Click on the grey portion at the bottom of the text chat and write your message. Then press Enter.
John: Just press Enter.
Moral: current is strong...
Vance: Yes, Moral? I'm curious about this. What does it do?
Moral: Vance, Why are you interested in a circuit break.
Vance: Because I don't know how it works
John: He wants to become an electrician.
Vance: So it creates a vacuum in my mind
Maggi: he has to know Moral...LOL
Vance: And if I can learn how it works then I will know SOMETHING that ...
Moral: It is used to limit the current.
Vance: that Maggi doesn't KNOW
Ayman: I am sorry for not participating the conversation , my audio has a problem
Vance: ha ha ha
Maggi: otherwise we have to call him an airhead
John: Many of us have that problem from time to time, Ayman.
Moral: Motors would be burned if the current is too high.
Vance: I understand that, Moral.
Vance: But since you're an engineer, I thought you might know ...
Vance: what is it about the strong current that makes the switch trip?
John: Moral, why does it just turn off the switch instead of burning it out like a fuse?
Maggi: sheesh...I guess I have to go get my book...
Vance: Yes, in a fuse, we can see that the current makes heat and the heat burns through the fuse
Vance: So why does a circuit breaker trip? This is everyone's assignment for next time!!

John: Vance, Maggi will be back in a minute.
John: Was it a circuit breaker problem?
Vance: probably
John: Better late than never.
John: Maggi had to go to the little girls room. [Marina wants to talk to Maggi because she has received a request to add a mysterious new person to her ICQ list, and she wants to check with Maggi is the person is a Webhead. She can't remember the name exactly, so we bounce a few off her - gvs]
Vance: grisham?
Vance: Sr. N
Vance: smith [Vance asks in voice chat to John how his phd is coming - gvs]
John: Vance, I am still waiting for the Institutional Review Board for the Protection of Human Subjects to give me my authorization.
John: Well, first, I'll be asking you three for interviews.
Marina: Hi, Maggi
John: I noticed that in the research I read.
John: I will be sending you an e-mail about everything that has been going on.
John: It is always good to be careful, Marina.
John: How many people are in your classes, Marina?
John: I might be able to find that many. I have 115 students in four classes.
John: If you contact me at either prof@jhsteele.com or at j_steele@cora.upr.clu.edu I'll tell you more about my classes.
