Power factor of a Schering bridge is _________(a) p.f. = sin∅x = ^Zx

1.	Power factor of a Schering bridge is _________(a) p.f. = sin∅x = ^Zx⁄Rx(b) p.f. = cot∅x = ^Rx⁄Zx(c) p.f. = cos∅x = ^Rx⁄Zx(d) p.f. = tan∅x = ^Rx⁄ZxI have been asked this question during an online exam.The question is from Schering Bridge topic in division Measurement of Inductance and Capacitance of Electrical Measurements
Answer» Right option is (c) p.f. = cos∅x = ^RX⁄Zx Easy explanation: The power FACTOR of the RC combination in a Schering BRIDGE is given by the relationp.f. = cos∅x = ^Rx⁄Zx . where, Rx is the series resistance Zx is the series IMPEDANCE comprising of Rx and Cx.
