Applications of Dimensional Analysis

If current (I), kinetic energy (K) and charge (Q) are taken as the fundamental quantities, The dimensional representation of power will be:

Show answer and solution

Answer: (b)

Power = energy/time, and time $t = Q/I$ .
$P = K/(Q/I) = KIQ^{-1}$ .
So the answer is (b) $[KIQ^{-1}]$ .
