Question

If 10^20 electrons are moving every second from west to east direction in a conductor, then the value and the direction of electric current in the conductor will be? Will it be x A west to east or x A east to west?​

Answer 1

Answer:

= \frac{Q}{T}

T

Q

Where I is current, Q is the total charge, T is the time taken.

T is 1 second ( as they have given it moves every second )

Charge on 1 electron is 1.6 × 10^{-19}10

−19

Number of Electrons = 10^{20}10

20

Total Charge = 1.6 × 10^{-19}10

−19

× 10^{20}10

20

Total Charge = 1.6 × 10^{1}10

1

= 1.6 × 10 = 16 A

Flow of Current is always opposite
