The frequency of revolution of electrons...

The frequency of revolution of electrons of electron in its orbit arount some nucleus is `3xx10^(15)` revolutions per seconds .
If we consider the motion of electron as one loop of current , what should be the magnitude of equivalent electric current ?

To find the equivalent electric current due to the motion of an electron in its orbit, we can follow these steps: ### Step 1: Understand the relationship between current, charge, and time. The electric current (I) can be defined as the amount of charge (Q) passing through a point in a circuit per unit time (T). Mathematically, it is expressed as: \[ I = \frac{Q}{T} \] ### Step 2: Relate frequency to time. The frequency (f) of revolution is the number of revolutions per second. The time period (T) for one complete revolution is the reciprocal of the frequency: ...
