Re: [Phys-l] Thermal heating in a resistor?

Why is the formula P=I^2R used to describe thermal power loss in resistor
instead of P=IV or P=V^2/R? Is this just the textbook author's choice of
formula?

Arguably, the choice of units is to reflect the underlying reality:
current passing against a given resistance is the basis for heating...
