IN HYDROGEN ATOM,THE ELECTRON MAKES 6.6* 10 RAISE TO THE POWER BY 15 REVOLUTIONS PER SECOND AROUND THE NUCLEUS IN AN ORBIT OF RADIUS 0.5*10 RAISE TO THE POWER-10m .THE EQUIVALENT CURRENT FLOWING IS APPROXIMATELY A- 10 RAISE TO THE POWER -2A B- 10 RAISE TO THE POWER -3A C- 10 RAISE TO THE POWER -4A D- 10 RAISE TO THE POWER -5A AND PLEASE EXPLAIN THE CALCULATION HOW?

Expert Answer:

Since the electron passes any specific point on the circumference on it's orbit 15 times a sec, we can say 15 electrons pass at a point in a second.
Equivalent Current = 2πfe =2x3.14x6.6x1015x1.6x10-19 ~ 10-4 A
