If 300 joule of work is required to be done to transfer 30 coulombs of charge, then the potential difference between two ends of battery is________.
10 V
Given:
Work done W = 300 joule
Charge Q = 30 coulomb
Let V be the potential difference across battery.
Work done is given by W=V×Q
Or, potential difference V=WQ=30030=10 V
