The dimensions of electrical conductivity are ……..

Explanation

To find the dimensions of electrical conductivity, we will follow a systematic approach. Let's break it down step by step.

### Step 1: Understanding Electrical Conductivity
Electrical conductivity (σ) is defined as the reciprocal of resistivity (ρ). Therefore, we can express it as:
\[ \sigma = \frac{1}{\rho} \]

### Step 2: Relating Resistivity to Resistance
Resistivity (ρ) can be expressed in terms of resistance (R), length (L), and area (A) using the formula:
