Question

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

Answer 1

Answer:

Electric current, $\dfrac{ne}{t}$

Explanation:

It is given that, n electrons are flowing through a cross section of a conductor in time t. We have to find the current in a conductor, if the charge of the electron is e.

The ratio of total electric charge per unit time is called electric current. If there are n electrons flowing through the conductor, then the total charge will be n times charge of an electron.

Mathematically, it can be written as :

$I=\dfrac{q}{t}$

Here, q = n × e

$I=\dfrac{ne}{t}$

Hence, this is the required solution for the electric current flowing in a conductor.
