The question as text
A student is investigating the potential difference in a circuit. The circuit is set up as shown in Fig. 2.1. V E P Q Fig. 2.1 Two resistors P and Q are connected in series to a power supply of electromotive force (e.m.f.) E and negligible internal resistance. Resistor P has resistance P. The potential difference V across resistor P is measured. The experiment is repeated for different values of P. It is suggested that V and P are related by the equation V = ( P P + Q) E where Q is the resistance of resistor Q. The value of Q is kept constant. 1 1
