Question

A conductor carries a current of 0.4 Ampere. Find the amount of charge that will pass through the cross section of the conductor in 1.5 minutes. How many electrons will flow in this time.

Answer 1

$\huge\mathfrak\pink{\underline{\underline{AnSwer}}}$

★ Formula to be applied is

I = Q/t

where, q = ne

n = number of electrons

e = charge on electron

I = ne/t

n = I × t / e

n = 0.4 × 1.5 × 60 / 1.6 × 10^-19

n = 2.25 × 10^20
