Detailed Solution

The work done by one coulomb of charge in passing through a 6 V battery is 6 J.
Given data,
Charge,

q = 1 C

Potential difference,

V = 6 V

.
It is known that “The potential difference between two points is said to be one volt when one joule of work is done to carry a charge of one coulomb between the two points in the electric field.”

V = \frac{W}{q}

Where,
V=Potential difference
W= work done
q=charge
Hence, the work done by the charge is given by

W = q \times V

On substituting the values, we get the work done as

W = 1 \times 6

= 6 J

Hence the work done by the charge would be

6 J
