A moving coil galvanometer shows deflection of 100 divisions when 20 A current is passed through it.If resistance of galvanometer coil is `50ohm` ,then find voltage sensitivity of galvanometer.

Galvanometer shows deflection when current passes through it. This is because,

A moving coil galvanometer needs a current of 100muA for a full scale deflecion of 50 divisions. If the resistance of the galvanometer is 1000 Omega, then its current senstivity is

A galvanometer shows full scale deflection when a current of 1 mA is passed through it . The resistance of the coil used in galvanometer is 100 Omega How will you convert it into an ammeter which should be able to measure the current up to 5 A ?

The deflection in a moving coil galvanometer falls from 100 divisions to 20 divitation when a shunt of 12 Omega is used. The resistance of the galvanometer coilds is

The deflection of a moving coil galvanometer reduces to half on shunting it with a resistance of 60Omega . The resistance of galvanometer is

What is the voltage sensitivity of a galvanometer if it requirs 100 mV for a full - scale deflection of 60 divisions ? Also calculate the resistance of the galvanometer coil if its current sensitivity is 2 divisions / muA .
