Question : 25

Total: 50

A charge of 10 C is transferred across a potential difference of 220 V. Determine the work done.

22J
2200J
210J
230J

Solution:

Concept:

The work done in moving a charge through a potential difference is given by

W = QV

.

Explanation:

Work done,

W = QV

.

Here, charge,

Q = 10 \, \mathrm{C}

and potential difference,

V = 220 \, \mathrm{V}

.

Substitute the values:

W = 10 \times 220

.

So,

W = 2200 \, \mathrm{J}

.

Answer:

The work done is

2200 \, \mathrm{J}

.

Correct option: B.
