An ammeter has a resistance of 50 ohms and a shunt of 0.01 Ω. The deflection is θ. If the shunt resistance is increased to 0.02 Ω, the deflection will be.-A-θB-2θC-0.5θD-0.25θ-B-2θ

Question

An ammeter has a resistance of 50 ohms and a shunt of 0.01 &Omega;. The deflection is &theta;. If the shunt resistance is increased to 0.02 &Omega;, the deflection will be.-A-&theta;B-2&theta;C-0.5&theta;D-0.25&theta;-B-2&theta;

APTITUDE CRACK · Accepted Answer

B 2&theta; Since shunt resistance is doubled, current through ammeter is doubled (current division for resistances in parallel). Therefore reading is 2 &theta;.
