Question

A galvanometer having a resistance of shows deflection of divisions

Answer 1

A galvanometer having 50 divisions provided with a variable shunt S used to measure the current as ammeter when connected in series with a resistance of 90 ohm and a battery of internal resistance 10 ohm, it is observed that when the shunt resistance are 10 and 50 ohm, the deflection are respectively 9 and 30 divisions ..

Answer 2

A galvanometer having a resistance of 20 and 30 divisions on both sides has figure of merit 0.005 ampere/division. The resistance that should be connected
