The current flowing through a conductor is given by `I="ne"Av_(d)`. (i) Identify each term in the equation. (ii) Obtain an expression for `V_(d)`, if the current flowing through the conductor of length / has its ends maintained at a potential difference V volt.

Explanation

To solve the problem step by step, we will break down the equation and derive the required expression for the drift velocity \( V_d \).

### Step 1: Identify each term in the equation \( I = n e A V_d \)

1. **Current (I)**: The flow of electric charge through the conductor, measured in Amperes (A).
2. **n**: The number of free charge carriers (electrons) per unit volume in the conductor, measured in \( \text{m}^{-3} \).
3. **e**: The charge of an electron, approximately \( 1.6 \times 10^{-19} \) Coulombs (C).
4. **A**: The cross-sectional area of the conductor, measured in square meters (\( \text{m}^2 \)).
