Question

a cell supplies the current of 0.4A when connected to an electric device. find the no of electrons flowing in given point of time​

Answer 1

Answer:

2.5x10^18

Explanation:

current=charge/time

0.4A=1.6x10^-19 x n/1    ( charge =  basic elementary charge x no. of electrons)

0.4/1.6x10^-19=n

n=2.5x10^18
