Question

If the electron in a Hydrogen atom makes 6.25x1015 revolutions in one second, the current is​

Answer 1

Explanation:

revolving electron can be assumed as equivalent current. We consider current in one time period, Therefore, the charge crossing in one time period is e.

I= T/Q

We know ,f=1/T

⇒I=Q×f ... (1)

Step 2: Finding Current

Put the values in equation (1)

I=Q×f

=1.6×10^−19C×6.25×10^15

=10^−3 A=1mA
