In a potentiometer wire experiment the emf of a battery in the primary circuit is 20V and its internal resistance is 5 ohms.There is a resistance box(in series with the battery and the potentiometer wire) whose resistance can be varied from 120 ohm to 170 ohm. Resistance of the potentiometer wire is 75 ohm. The following potential differences can be measured using this potentiometer: a)5V b)6V c)7V d)8V
