Question

An electron in hydrogen atom
makes 6.0 x 10-15 cycles per second
round the nucleus. What will be
the value of current at a point on
the circular part ? The charge on
electron
1.6 x 10-19
coulomb. ​

Answer 1

Explanation:

The current is also produced by a charged particle and it can be said as charge flowing per unit time……

I=q/T

Consider “I” as current, “q” as charge on the electron and “T” as the time period of the electron.

Here Inverse of Time period i.e., 1/T can also be written as frequency (number of revolutions per second) lets call it as “n”

So we can rewrite the equation as

I=q×n

As we know that the charge of electron is quantised and its value is 1.6×10^-19 i.e., the value of “q”.

And as per the given value of frequency i.e., 6.26×10^15

By that we can calculate the current in the electron it constituted.

I=q×n

I=1.6×10^-19 × 6.26×10^15

I=10.016×10^-4 Amps
