The diagram shows a battery of electromotive force (e.m.f.) 6 V, connected in series with a resistor and a uniform resistance wire RQ of length 60 cm.
The resistance of RQ is equal to the resistance of the resistor.
Terminal X is connected to fixed point R. Terminal Y is connected to point P, a connection that may be made at any position along the wire. L is the distance between R and P.
Which graph shows the variation with L of the potential difference (p.d.) V across XY?
