I am starting a grassroots campaign and I want your support. Lets get rid of the craziness and drop the use of "E" and "I" as representations of voltage and current. What is wrong with the use of "V" and "A"? I know we in the electrical industry are hard to give up tradition and history, but change is good, when it makes sense.

It is important to explain the fundementals of electromotive force, but using "E" does not serve any purpose except confusion. The same goes for "I" and it's unknown origin, perhaps intensity.

For now on, I will no longer use the formula E=IxR. I ask you to do the same! V=AxR!

I'll make some posters! We could text message a Flash Mob and get down to the Peavey Plaza in time for the evening news. . .whadya say?
 
Re: Down with the E and I

I'm always on a campain similar to this one but it really sounds stupid when someone else says it. :)

For what it's worth I'm on your side Bryan.
:D
 
Re: Down with the E and I

Come on! Let's go!

If we do this we can really upset the guys over in the Physics Department.

They won't know what hit'em.
 
Re: Down with the E and I

You guys are a bunch of trouble makers, I think I will take away your hall passes and report you to the principal.

Re: Down with the E and I

"E" and "I" represent the parameters (voltage and current). "V" and "A" represent the units of measure (volts and amps). Sorry, I can't go along with you on this one. :( ;)
 
Re: Down with the E and I

I can't help but ask Charlie B., what does the "E" in the one case and the "V" in the other signify?

VA is used instead of watts in order that true and appearant power aren't confused.

But the V in voltage is the same as the E in electromotive force. They describe the same attribute of reality.

Edit: To be less sloppy.

Re: Down with the E and I

After changing "P" to "W", we were able to atach the word "WIRE" to the commonly used "OHMS LAW WHEEL". Now, if we change "I" to "A" and "E" to "V" we will have to change this to "WARV", or if we go back to using "P", it would be "PARV"

I don't know about this. :D

Re: Down with the E and I

Roger, I'm trying to focus, I have to be on my toes when I disagree with Charlie. :D
 
Re: Down with the E and I

I agree with Charlie B in principle, but "e" is only used to indicate emf, while "v" is used to indicate the units of any emf or voltage and also to indicate the value of voltage in general.

Sam, we should really say that apparent power is,

Pa = VI in Volt-Amperes, but don't expect that to change.

Sort of like a ROM is a RAM unless it is a CD ROM in which case it is a SAM.

This stuff is hard enough to get right without messing with the nomenclature.

Re: Down with the E and I

Ok, fair enough distinction.

Electromotive Force is expressed in volts. Rather than the two being synonymous.

And all of a sudden I'm on Charlie's side.

Re: Down with the E and I

Actually Roger I thought it was rather thoughtful. But when I was in the middle of tidying up my post I looked down at yours and got all side tracked looking at your acronymn datadase. :D
 
Re: Down with the E and I

I have always had the understanding that when you are refering to a generated or induced voltage it is "E". As in an equation like Ohms law.

When you are refering to a line voltage you use "V", as in 480V.

Same goes for current, "I" refers to current but when you put a value on it you use "A", as in 50mA.
 
Re: Down with the E and I

In the old days, I learned, when used in formulas:
V and E are both quantities which are measured in units of volts.

V->a scalar quantity - DC volts
E->a vector quantity - AC volts
 
Re: Down with the E and I

I just checked one of my old textbooks. It states early on that it will use "V" and "I" for the parameters voltage and current, with vertical bars around the letter, such as /V/, to denote the scalar quantity of their magnitude. This same book (and many others) use the letter "E" to denote the generated voltage from the model of a generator (consisting of an ideal voltage source in series with the internal impedance of the machine). So it seems that the only consistent answer is that there is no consistent answer. :D
