Question

7) How many electrons constitute 0.16C of charge?
8) A current of 12 A flows across a conductor for 5s. Find the number of
electrons flowing across it?

Answer 1

Explanation:

7) Multiply that with 16, and it will give you 1x10^20 electrons in 16 coulombs of charge.

8.Total charge that flows in 2s is given by

q=It=5×2=10C

Now, charge on one electron is given by e=1.6×10

−19C

N= number of electrons

q=Ne

⟹N=q/e

⟹N= 10/1.6x10-¹⁹

⟹N=6.25×10 19
