Question

To move charge q from point a to point b requires –30 J. Find
the voltage drop vab if: (a) q = 2C, (b) q = – 6C

Answer 1

Answer:

a). -15 V

b). 5V

Explanation:

workdone in bringing charge from a to b is - 30 J.

voltage drop across the battery will be potential difference i.e. terminal voltage..

from relation..V=W/Q.

a). V= -30J/ 2C = -15 V

similarly.

b). V=5V
