Answer:

Explanation:

=>Here, In an atom electron revolves around the nucleus along a path of radius 0.72A making 9.4×10^18 revolution per second.

∴ R = 0.72A

f = 9.4 * 10¹⁸

equivalent current I = ?

=> equivalent current, I = Q/t = e/T

But, T = I/f

=> I = e * f

= 1.6 * 10⁻¹⁹ * 9.4 * 10¹⁸

= 15.04 * 10⁻¹

= 0.15 * 10⁻³ A

I = 0.15 mA

Thus, the equivalent current is 0.15mA.

Answer:

1.5 A

Explanation:

∴ R = 0.72A

f = 9.4 * 10¹⁸

equivalent current I = ?

=> equivalent current, I = Q/t = e/T

But, T = I/f

=> I = e * f

= 1.6 * 10⁻¹⁹ * 9.4 * 10¹⁸

= 15.04 * 10⁻¹

= 1.5 A

I = 1.5 A
