Given information
It is given that :
Current
Shunt resistance
Galvanometer Resistance
Full scale reading of the voltmeter =
Step-by-step explanation
Step 1.
The resistance in ammeter must be very small such that there is no potential difference across it. In order to achieve it we connect shunt resistor in parallel with the
galvanometer
Hence, equivalent resistance of ammeter is,
