Question

calculate the amount of current which flows through a conductor if 10 electrons cross its one point in 10 sec ​

Answer 1

Answer:

Current =  Charge / time 

we know that ,

1 e⁻ has 1.6 x 10⁻¹⁹ Coulomb charge.

So charge here on 10 e⁻ = 1.6 x 10⁻¹⁹ × 10= 1.6 x 10⁻¹⁸ C

Now by formula -

 I= q/t

I = 1.6 x 10⁻¹⁸ ÷ 10

⇒ 1.6 x 10⁻¹⁹ Ampere
