I am not.  As I near retirement, I discover that much of what I learned in high school and as a liberal arts college student was wrong or at least incomplete.  The "change" in Ohm's law is just a tiny part.  My geology course never mentioned tectonic plates.  My astonomy survey course never mentioned dark matter.  The Freudian psychology I studied is now commonly regarded as quaint at best.  "Nanook of the North" is now regarded as a poorly made almost fraudulent film rather than a fine sociological study.  Margaret Mead is often now seen as a deceived and naive woman rather than as a great anthropologist. 

I suppose my frequent and deliberate on-the-air references to condensers, megacycles and the Class A phone bands are a reaction to this.

 I said "Sorry".  I too am approaching retirement.  You should see the faces on my students when I accidentally write E=IR on the board instead of V=IR.

Consider yourself lucky you don't have to deal with magnetism and have to deal with tesla's webers, gauss, and oersteds andwhich system of units they are.  It gets ugly.

and P = Power ; R = Resistance; I represents Amperes

E = Electromotive Force
The I stands for Intensity, BTW.

Is that what I stands for?

It seems to me that many years ago, I read that I stood for something else, but I'll be darned if I can remember what.

But I'll take your word for it, since I don't have a better explanation. :-)

It was too long ago for me also, I may be "remembering" the wrong word.  Yet again...

then there's Schmo's law... if you hose up your Ohm's law calculations, all your answers are zero when the test comes back.

The thought occurs...
If...
E==IR then why even bother with E?
IR==IR.
I think therefore, I ARE!
Maybe, I can measure just how much I ARE with my VOM.
Just tried, and got 0.0 on the LCD display.
Which could mean that I AREN'T.
But if I AREN'T then you never read this.
Unless you AREN'T?
Maybe we all AREN'T!

Theoretical Physicists are indeed tackling the idea that this is a holographic universe...
