Question : 29

Total: 90

In a circuit for finding the resistance of agalvanometer by half deflection method,a 6 V battery and a high resistance of 11 kΩ are used. The figure of merit of the galvanometer is 60µA/division. In the absence of shunt resistance, the galvanometer produces a deflection of θ=9 divisions when current flows in the circuit. The value of the shunt resistance that can cause the deflection of θ/2, is closest to :

550Ω
220Ω
55Ω
110Ω
