Ten million electrons pass from point p to q​

Answer 1

Answer:

Here, number of electron, n=10000000=10

7

Total charge on ten million electrons is

Q=ne[Where e=1.6×10

A

Since the direction of the current is always opposite to the direction of flow of electrons. Therefore due to flow of electrons from point P to point Q the current will flow from point Q to point P.
