What is the relation between conductance and conductivity ?

Explanation

To understand the relationship between conductance (G) and conductivity (σ), we can break it down into a few steps:

### Step-by-Step Solution:

1. **Define Resistance (R)**:
- Resistance is defined as the opposition to the flow of electric current. It is given by Ohm's law:
\[ R = \frac{V}{I} \]
- Here, \( V \) is the voltage (in volts) and \( I \) is the current (in amperes). The unit of resistance is Ohm (Ω).
