Question

100 Joule of work is done in moving 20 coulomb of charge from one end to another the potential
difference between the two ends of the conductor will be
(A) 10 V
(B) 100 V
(C) 5 V
(D) 20 V​

Answer 1

Answer:

(C) 5 V

Explanation:

V = W/Q

  = 100/20

  =5 V

Answer 2

Work done: 100 J

Charge Q = 20 C

Current I = 2 A.

Finding potential difference V from the relation of work done on a particular charge.

V=W/Q

V= 100J/20C

V= 5 volts.

The potential in the circuit is 5 Volts.

Hence option is (C)
