Two galvanometer A and B require the current of 4 mA and 7mA repectively to produce the same deflection of 20 divisions. Then

When 3 mA and 5 mA currents are passed through two galvanometers P and Q, they give same deflection of 10 divisions. Hence

A current of 10 A produces a deflection of 45^(@) in a tangent galvanometer. What is the value of the current which will produce a deflection of 30^(@) in the same galvanometer?

The resistance of a galvanometer is 2.5Omega and it requires 50mA for full scale deflection. The value of shunt resistance required to convert it into an ammeter of range 0 to 5A is
