Question

In a hydrogen atom an electron is revolving with an angular frequency 6.28rad/s around the nucleus then equivalent current is

Answer 1

Given:

In a hydrogen atom an electron is revolving with an angular frequency 6.28rad/s around the nucleus  

To find:

The equivalent current is

Solution:

From given, we have,

In a hydrogen atom an electron is revolving with an angular frequency 6.28rad/s around the nucleus

we use the formula,

I = q/t

now, we will find the frequency,

ω = 2πf = 6.28 rad/s

f = 6.28/(2 × 3.14) = 1 Hz

time period is given by,

t = 1/f =1 s

Thus the equivalent current is given by,

I = e/1 = 1.6 × 10−19 A

Therefore, the equivalent current is 1.6 × 10−19 A
