The resistance of the coil of a tangent galvanometer is `60Omega`. It is connected to a battery of negligible internal resistance. The deflection is found to be `60^(@)`. Now a shunt resistance of `30Omega` is connected across the coil of the tangent galvanometer. The deflection produced will be

The resistance of a galvanometer is 100Omega . A shunt of 5 Omega is connected to it to convert it into an ammeter. The internal resistance of the ammeter is

A galvanometer of resistance 5 Omega is connected in series with a resistance of 0.2Omega to a battery of negligible internal resistance. The deflection is noted. If the 0.2Omega resistance is replaced by 2 Omega resistance, the value of shunt resistance to be connected to the galvanometer to maintain the same deflection is

The deflection of a galvanometer falls to 1//10^(th) when a resistance of 5Omega is connected in parallel with it. If an additional resistance of 2Omega is connected in parallel to the galvanometer, the deflection is

The deflection of a galvanometer falls to 1//10^(th) when a resistance of 5Omega is connected in parallel with it. If an additional resistance of 2Omega is connected in parallel to the galvanometer, the deflection is

The deflection in a MCG is reduced from 40 divisions to 10 divisions, when a shunt of 10 Omega is joined across it. What is the resistance of the galvanometer coil ?

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

A cell of negligible internal resistance is connected to a tangent galvanometer and the deflection produced is 30^(@) . If theree such cells are connected in series and the combination is connected to the same galvanometer, the deflection will be
