Question

53. How many electrons pass through a conductor in 0-2s, if the current passing through it is 0.5A
[Ans​

Answer 1

HEYA GM ❤

★ Q ( CHARGE ) = n × e ...1°

★ Q ( CHARGE ) = Current × Time .... 2°

»» Equating Both EQUATIONS .. 1 & 2 we get ;

» I × t = n × e

» 0.5 (given) × 2 (given) = n × 1.6×10^-19

» 1 / 1.6 × 10^-19 = n ( no. of electrons )

»« n = 625 × 10^-22 electrons ....

Answer 2

Answer:

Explanation:

Given  :-

I = 0.5a

T= 0.2sec

To Find :-

Numbers of electron.

Formula To be used :-

I = q × t

Q = I × t

Solution :-

Q = 0.5 × 0.2

= 0.10

One electron consist

1.6 × 10⁻¹⁹ c

Q = N × e

N = q  × e

N = 0.10 × (1.6 × 10⁻¹⁹)

N = 6.25 × 10¹⁷ electron

Hence, the numbers of electrons is 6.25 × 10¹⁷ electron.
