Solution

The correct option is D $V = \frac{U}{I t}$
Since power through a load is $I V$ , energy, $U$ is $U = V I t$ .

Hence $V = \frac{U}{I t}$ .

Let I = current through a conductor, R = its resistance and V = potential difference across its ends. According to Ohm's law, product of two of these quantities equals the third. Obtain Ohm's law from dimensional analysis. Dimensional formulae for R and V are $M L^{2} I^{- 2} T^{- 3}$ and $M L^{2} T^{- 3} I^{- 1}$ respectively.
