Galvanometers are used for electrical measurements.
Write a short note on the galvanometer.
In an ammeter, 20% of the main current passes through the galvanometer. If the resistance of the galvanometer is G, then the shunt resistance in ohms is
A moving coil galvanometer of resistance 20 Ω gives a full scale deflection when a current of 1 mA is passed through it. It is to be converted into an ammeter reading 20 A on full scale deflection. If a shunt wire of 0.005 only is available, then what resistance should be connected in series with the galvanometer coil?
A galvanometer of resistance ‘G’ can be converted into a voltmeter of range (0 − V) volt by connecting a resistance ‘R’ in series with it. The resistance ‘R’ required to change its range from `(0 - V/4)` volt will be ______.
