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

Answer»

<P>P is more SENSITIVE than Q.
Q is more sensitive than P.
P and Q are both EQUALLY sensitive.
Sensitivity of Q is `5/3` times sensitivity of P.

Solution :Because for same DEFLECTION, `S_(i)prop1/I`
