Question

The electromotive force of a cell is 1.5 V. The work done on passing a charge of 1 C will be:

• A. 1.5 V
• B. 3 J
• C. 1.5 J
• D. 0 \bigskip

Hint:

The work done in moving a charge through a potential difference is the energy transferred to the charge.

Answer 1

The Correct Option is C

The work done \( W \) is given by: \( W = V \times Q \), where \( V = 1.5 \, \text{V} \) and \( Q = 1 \, \text{C} \). Thus, \( W = 1.5 \, \text{V} \times 1 \, \text{C} = 1.5 \, \text{J} \).
