Question

IN hydrogen atom ,an electron is revolving with angular frequency 6.28rad/sec around the nucleus .then the equivalent electron current is_*10 to the power -19

Answer 1

$$\begin{gathered} I=q/t \\ \omega =6.28rad/s=2\times 3.14\times f \\ f=\frac{6.28}{2\times 3.14}=1Hz \\ t=1/f=1s \\ I=\frac{e}{1}=1.6\times {10}^{-19}A \end{gathered}$$
