A galvanometer measures current which passes through it. A galanometer can measure typically carrent of order of mA. To be able to measure currents of the order of amperes of main current, a shunt resistance 'S' is connected in parallel with galvanometer.

The resistance of the shunt 'S' and resistance 'G' of the galvanometer should have the following relation.

`S=G`

`SgtgtG`

`SltltG`

SltG`

Text Solution

Verified by Experts

The current through the galvonometer is `~1/1000` of total current, the `SltltG`.
