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

Answer 1

Answer:

I (current )= Q (charge )/ T (Time)

charge of a electron is 1.6×10^-19 Columb

charge of 10^20 electron is 1.6×10^-19×10^20

= 1.6×10 =16 Columb

I = 16 C/1 Sec = 16 Ampere

16 Ampere of current flowing through conductor in the direction of charge that is from west to east.

Answer 2

Answer:

16 A, East to West

Explanation:

I = $\frac{Q}{T}$

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 × $10^{-19}$

Number of Electrons = $10^{20}$

Total Charge = 1.6 × $10^{-19}$ × $10^{20}$

Total Charge = 1.6 × $10^{1}$ = 1.6 × 10 = 16 A

Flow of Current is always opposite to flow of electrons, as current flows from positive terminal ( protons )
