At high Q values, the angular balance condition is _________(a) satisfied(b) not satisfied(c) independent of Q factor(d) partially affectedI had been asked this question by my school teacher while I was bunking the class.The doubt is from Advantages and Limitations of Maxwell Bridge in section Measurement of Inductance and Capacitance of Electrical Measurements |
Answer» RIGHT option is (b) not SATISFIED The best explanation: For high Q factor VALUES in a Maxwell inductance capacitance bridge, the angular balance condition is affected. The relation θ1 + θ4 = θ2 + θ3 is not satisfied at high Q factor values. This occurs as θ4 reaches 90°. θ1 must become –90° as per the angular balance condition. But for this the value of R1 should be very high, which is not practically feasible. |
