R Circuit


What is this for?

Power equation in Load section
Please don't crucify me if I'm wrong here. I'm not an electronics wiz. In fact, I came here because I want to read about electronics, not write about it. But I do know some algebra, and I believe there is a mistake under the Load section where Ohm's law is substituted (substituDed?) into the power equation.

If $$P=VI\!$$, and $$V=IR\!$$, then wouldn't $$P=\left(IR\right)I\!$$, or $$I^2R\!$$, instead of $$IR^2\!$$?

If $$P=VI\!$$, and $$I=\frac{V}{R}$$, then wouldn't $$P=V\left(\frac{V}{R}\right)$$, or $$\frac{V^2}{R}$$, instead of $$\frac{V}{R^2}$$?

I'd just like to say that this page is very informative - keep up the good work! 81.77.59.126 16:42, 7 March 2006 (UTC)

Symbols
it appears to me that the page uses the pre-ISO symbol for resistors, would it be appropriate to update it?
