If the current density is 1.55 and the drift velocity is , how many charge carriers are present? The charge on electron is .(Enter your answer to three significant figures.)

There are charge carriers.

Explanation:

Given that,

Current density (current per unit time),

The drift velocity of the electron,

We need to find the no charge carriers present. The formula for drift velocity is given by :

So, there are charge carriers.
