Why does power supply decrease when you add additional resistors in series? (For example, using 3 resistors in series versus 4 resistors in series) I understand that as you increase the number of resistors in series, it increases the equivalent resistance. If the equivalent resistance increases, and the voltage stays the same, then the current decreases (V=IR). Then you can say P=V^2/R, which means that the power decreases, right? But shouldn't the total power be the same as the first...
