Question

How many electrons will flow for the flow of charge of
40C in 12 sec? (Charge on 1 electron = 1.6 X10-19 C)​

Answer 1

Explanation:

1 coulomb =6.25×10^18

40 coulomb =40×6.25×10^18

=250×10^18 electrons

Answer 2

Answer:

3×10²¹

Explanation:

If 40C flow for 12 sec, the charge in C is 12×40=480C

Dividing it by the charge of one electron, we get the number of electrons.

Hence, no. of electrons=480/1.6×10⁻¹⁹=3×10²¹
