Marks: +1, -0

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?

A 6.66 mΩ shunt resistor is to be connected in series with the galvanometer
A 10.55 mΩ shunt resistor is to be connected in series with the galvanometer
A 10.55 mΩ shunt resistor is to be connected in parallel with the galvanometer
A 6.66 mΩ shunt resistor is to be connected in parallel with the galvanometer
