Question

If there are 10^8 electrons flowing across any cross section of a wire in 4 mins,what is the current in the wire??

Answer 1

Answer:

Explanation:

The current in the wire is 1.33 mA.

Explanation:

It is given that,

Number of electron,

Time, t = 2 minutes = 120 seconds

We need to find the current flowing in the wire. It is given by the net charge flowing per unit time such that,

Since, q = ne

I = 0.001333 A

or

I = 1.33 mA

So, the current in the wire is 1.33 mA. Hence, this is the required solution.
