Question

in a hydrogen atom an electron moves in an orbit of radius 5×10 power-11 with a speed of 2.2 ×10 power 6 m sec. inverse . find the equivalent current​

Answer 1

Answer -

I = 1.12 mA

Explanation -

Electric current formed due to motion of e- is -

I = Q / t

I = e / (2πr/v)

I = e.v / 2πr

Substitute values,

I = 1.6×10^-19 × 2.2×10^6 / (2 × 3.14 × 5×10^-11)

I = 1.12×10^-3 A

I = 1.12 mA

Therefore, electric current formed due to the motion of electron is 1.12 mA.
