n electrons flow through a cross section of a conductor in time t. If charge on an electron is e, then write an expression for the current in the conductor.

Explanation

To derive the expression for current in a conductor when n electrons flow through a cross-section in time t, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of electrons (n)**: The problem states that n electrons flow through a cross-section of the conductor.

2. **Determine the charge of one electron (e)**: The charge on a single electron is given as e.
