Q: If C and R denote capacitance and resistance respectively, then the dimensional formula of CR is

(a) [M0L0T]

(b) [M0L0T0]

(c) [M0L0T-1]

(d) Not expressible in terms of [MLT]

Ans: (a)

Sol: As the product CR is known as time constant , hence its dimensional formula is equal to dimensional formula of time i.e.

[M0L0T]
