The dimensional formula is defined as the expression of the physical quantity in terms of mass, length, time and ampere.
Explanation-
Power – It is defined as rate of doing work.
\(\therefore P = \frac{W}{t}\)
Where, P = power, W = work done and t = time.
Now,
Dimensional formula of work (W) = [ML2T-2]
Dimensional formula of time (t) = [T1]
\(P = \frac{{M{L^2}{T^{ - 2}}}}{{{T^1}}} = \frac{{M{L^2}}}{{{T^3}}}\)
∴ The dimensional formula of power P is [ML2T-3].
