Grade 12th passElectric Current
Three arms of Wheatstone bridge have resistance of 100Ω & fourth arm of 100.01 Ω A galvanometer of 50 Ω resistance & 0.05 A/mm of sensitivity is connected across one diagonal of the bridge. A battery of 3 V e.m.f is connected in series with a resistance of 200 Ω to the other diagonal find the deflection in the galvanometer.
