(A) Voltage $(V)$ is defined as the work done $(W)$ per unit charge $(Q)$ to move a charge between two points.Mathematically,$V = \frac{W}{Q}$.We know that electric current $(I)$ is the rate of flow of charge,given by $I = \frac{Q}{t}$,which implies $Q = I 	imes t$.Substituting this value of $Q$ into the voltage formula,we get $V = \frac{W}{I 	imes t}$.Therefore,voltage is represented by $\frac{	ext{Work}}{	ext{Current} 	imes 	ext{Time}}$.
