1.	Angular balance equation is given by which of the following relation?(a) θ1 × θ4 = θ2 × θ3(b) θ1 + θ4 = θ2 + θ3(c) θ2 + θ4 = θ1 + θ3(d) θ2 × θ4 = θ1 × θ3The question was posed to me during an interview.My enquiry is from Bridge Balance Equation topic in division Measurement of Inductance and Capacitance of Electrical Measurements
Answer» Right answer is (B) θ1 + θ4 = θ2 + θ3 To explain I would say: The angular balance CONDITION in an AC bridge is given by the relation θ1 + θ4 = θ2 + θ3 Where, θ1, θ2, θ3 and θ4 are the phase angles of the impedances Z1, Z2, Z3 and Z4.
