The dimensions of RC is (a) square of time (b) square of inverse time (c) time (d) inverse time

Answer: (c). RC is the time constant of a charging capacitor ( q = q₀(1 - e-t/RC), exponent dimensionless). [RC] = [T] So the answer is (c) time.

The dimensions of $RC$ is

Show answer and solution

Answer: (c)

$RC$ is the time constant of a charging capacitor ( $q = q_0(1 - e^{-t/RC})$ , exponent dimensionless).
$[RC] = [\mathrm{T}]$
So the answer is (c) time.
