Question

An electron is moving in a circular path of radius 0.5 m with a period of 10⁻¹⁹ s. The current constituted in the circular path is:
(a) 0.1A
(b) 2.5A
(b) 1.9 A
(d) 1.6 A

Answer 1

d=1.6 (A)

may be

I hope the right answer

Answer 2

Answer:

Current constituted in the circular path = 1.6 amperes.

Explanation:

Current is defined as rate of charge in conductor. S.I. unit of the current is Amperes ($A$).

Current is given by the formula, $I=\frac{Q}{t}$

where, $I$ denotes current,

$Q$ is the charge,

$t$ is the time.

Given: time period = $t = 10^{-19}s$

Charge of an electron: $Q=1.6*10^{-19}C$

Current constituted in the circular path = $\frac{Q}{t} =\frac{1.6*10^{-19}}{10^{-19}} =1.6A$

Current constituted in the circular path = 1.6 amperes.
