Question 5 Electricity - Exercise

A current of 1 A is drawn by a filament of an electric bulb. Number of electrons passing through a cross section of the filament in 16 seconds would be roughly.

Answer:

Answer is (a) 10²⁰

Explanation:

I = Q/t

Q= It

Q= 1 x 16

Q= 16 q

Q=ne

n = Q/e

n = 16 /1.6 x 10^-19

n = 10 x 10¹⁹

n = 10²⁰ electrons

The number of electrons flowing is 10²⁰ electrons
