Vedclass · Answer

(A) Voltage $(V)$ is defined as the work done $(W)$ per unit charge $(Q)$ to move it between two points in an electric circuit.Mathematically,$V = W / Q$.Since electric current $(I)$ is defined as the rate of flow of charge,$I = Q / t$,which implies $Q = I 	imes t$.Substituting $Q = I 	imes t$ into the voltage formula,we get $V = W / (I 	imes t)$.Therefore,the correct formula is $	ext{Work} / (	ext{Current} 	imes 	ext{Time})$.

Which of the following formulas represents voltage $(V)$?
