Teaching UP PGT Mock Test Series 2024 Physics Moving Charges and Magnetism The Moving Coil Galvanometer
A galvanometer coil has resistance 20 Ω and the metre shows full scale deflection for a current of 2 mA. How will you convert the metre into an ammeter of range 0 to 6 A?
1
A 6.66 mΩ shunt resistor is to be connected in series with the galvanometer
2
A 10.55 mΩ shunt resistor is to be connected in series with the galvanometer
3
A 10.55 mΩ shunt resistor is to be connected in parallel with the galvanometer
4
A 6.66 mΩ shunt resistor is to be connected in parallel with the galvanometer
