An Electron Revolves In A Circle At The Rate Of Physics Question

An electron revolves in a circle at the rate of 10¹⁹ rounds per second. The equivalent current is (e=1.6×10⁻¹⁹C)

Options

(a) 1.0A
(b) 0.2A
(c) 0.1A
(d) 2.0A

Correct Answer:

0.2A

Explanation:

Current I = qf

Given, q = 16 × 10⁻¹⁹ C and f = 10¹⁹

Therefore, I = 1.6 A
