But I suppose I am as guilty as any. So go ahead and send me to the punitentiary. :D :D
 
Re: Down with the E and I

That's quite a leap on Dr. Steven Maturin's part. I wonder what his diagnoses look like. :D
 
Re: Down with the E and I

OK now, in algebraic terms,

v and e are voltage variables expressed in units of Volts.

i is the current variable expressed in units of Amperes.

R, L, and C, are constant circuit parameters expressed in units of Ohms, Henrys, and Farads.

Don't rock the boat!
 
Re: Down with the E and I

Actually I and current are synonymns. They are both equal to Q/t.

Edit: But that's not really useful though is it. Never mind, ignore me.

Re: Down with the E and I

I have been in upstate New York all week so maybe the high altitude is getting to me.

What makes "E" and "I" so important? Just because that's what has always been used? Sounds to me like the grounded/bonded arguement.

Voltage should be represented in formulas as "V", current as "A" and resistance can stay as "R".

You can still describe electromotive force but just drop the "E". And "I" makes absolutely no sense!
 
Re: Down with the E and I

I know what the E comes from but I don't know where the I comes from?

I don't see any reason we couldn't use VR&A, Except it looks really funny. :D I'm sure we'd adjust.
 
Re: Down with the E and I

Bryan, the answer is "because". Because that is the way the rest of the world does it. "I" is the accepted symbol for the current variable. "A" is the accepted symbol for the unit of current, the Ampere.

We do not measure "The Amps", we measure the current in Amperes. We could measure the Amperage in Amperes, but the symbol for current is still "I".

If you are serious about this, you are like Don Quixote, fighting windmills. :D
 
Re: Down with the E and I

Now I'm waffling back to Charlie and Rattus' side.

This doesn't seem that complicated but I'm drawn to both sides.

To extend Rattus' point:

Do you want to use the variable "O" for resistance.

E is Electromotive Force
V is from Alessandro Volta. This one's easy.
R is from Resistance. But Georg Ohm is where we get the unit Ohm.
I is from I don't know where but Andre Ampere is where we get amperes from.

It does seem a little lopsided to me.

Edit: I thought I should add E.

Along these lines, 'Current' should be 'C'.

But, I'm for keeping it the way it is.

Does "I" ever make sense? :D

P.S. Hope you had a nice time in NY.
 
Re: Down with the E and I

Talk about convoluted logic. We can not always abbreviate everything based on it's first letter. For example: Current, Capacitance, Conductance, and Charge which one should be C? How about Black, Blue, and Brown?

Remember we are dealing with quantities (i.e. volts, current, capacitance, and resistance) with the symbols (E or V, I, C, and R) and units of measure (i.e. volts, amps, farads, and ohms) their abbreviations (V, A, F, and the Greek letter Omega).

The whole confusion seems to be from the co-incidence that the quantity Volts has two different symbols E and V but only one unit of measure which has the same name.

My solution: don't use V in formulas only use E (I know old habits are hard to break).

Re: Down with the E and I

Lets get to the real problem:

Why are we using the greek letter omega for resistance when all the other electrical parameters have good ole english letters!!

Because:

And because "ohm" sounds like "Omega."

But don't confuse that with "mega-ohm." :D
 
Re: Down with the E and I

Steve, we use Omega because an "OH" would be too easily confused with a zero.

Being pedantic now, we should measure potential, current, resistance, and power in units of volta, amps, ohms, and watts.

However, "voltage" and "amperage" have become synonymous with potential and current, and I think I have heard the term "Ohmage". :(

Sorry, sometimes I just can't help myself.

Just how many times do we get to use code symbols? I think &#8486 is cool. I feel special cause I can use it in my writing.
