hello all! If there is a circuit with only one heating element, how do we calculate the power it requires? According to the physics formula P=V^2/R, whenever you increase the resistance, the power it requires falls. However, I don't think that's right. Or is it? When R is increased, so the heating element will consume more power right? So if you substitute a larger value of R in the formula, the P falls. Why is it so?
