QA- Three arms of Wheatstone bridge have resistance of 1000, and the fourth arm 1010
A galvanometer of 500 resistance and 0.1uA/mm sensitivity is connected across on diagonal
of the bridge, a battery of SV to other diagonal Find the deflection of the galvanometer
B-An ac bridge has the following constants, arm AB, a resistance of 3000 in series
with an inductance of 0.4H, BC, a resistance of 450002 in series with an inductance of 0.6H;
CD, pure resistance 35900, DA, pure resistance 241002 An oscillator maintains an emf of
1SV (rms) at w-2xf 10K radians per second between terminals A and C. the detector is a
telephone handset with impedance 1258-13600 12 at this frequency. Find the current that
flows in the detector for the above condition
