How do you know when to use which:
P= (V^2)/R or P=(i^2) *R
for the power of a resistor?
I expected to get the same answers for both equations but for some reason it didn't work when I was doing ek probs
and also... does anyone know why Vreal<Videal and moderately high pressures.. and can we still sub this lower Vreal into Van der Waals equation?
