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

Explanation

To find the dimensional formula of the product of capacitance (C) and resistance (R), we will follow these steps:

### Step 1: Determine the dimensional formula of capacitance (C)
Capacitance (C) is defined as the charge (Q) per unit potential difference (V). The formula for capacitance is:

\[ C = \frac{Q}{V} \]

We know that potential (V) can be expressed in terms of work done (W) and charge (Q):
