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
