Two Parallel Currents

Two identical...

Question

Two identical galvanometers are joined by connecting wires. One of them is placed on the table and the other is held in the hand. One in the hand is shaken violently so that it shows a deflection of 10 division. The reading in the other galvanometer (on the table) is

A

zero

Solution

The correct option is B 10 division
When $G_{1}$ shows a reading of 10 divisions
The current passing through it also passes through $G_{2}$ and hence it will also show the same reading.
