Answer 2

Hi dude!

Here is your answer..

1) Variable resistance is nothing but a resistance that can be altered.
It is also known as Rheostat.

For e. g. The rheostat of electric fans.

2) I = Q × t,
Therefore, I = 150 × 60 =9000 Amperes.

3) Q= n * e,
Therefore, n = 1/1.6 * 10^-19 = 6.25 * 10^18 electrons.

4) R = rho * L/ A,
Therefore, R = 0.0361290323 Ohm.

Hope it helps you..
