Question:
Which of the following represents voltage ?
(a) $\frac{\text { Work done }}{\text { current } \times \text { time }}$
(b) Work done $\times$ charge
(c) $\frac{\text { Work donex time }}{\text { current }}$
(d) Work done $\times$ charge $\times$ time
Solution:
(a).
Explanation: Voltage or electric potential
$=\frac{\text { Work done }}{\text { charge }}=\frac{\text { Work done }}{\text { current } \times \text { time }}$
( $\because$ Current $=$ Charge $/$ time $)$
