Wattmeters are compensated for errors due to inductance by _________(a

1.	Wattmeters are compensated for errors due to inductance by _________(a) using a series capacitor(b) using a parallel capacitor(c) using a series resistance(d) using a parallel resistanceI have been asked this question in my homework.This key question is from Errors in Dynamometer Wattmeter topic in division Measurement of Power and Related Parameters of Electrical Measurements
Answer» Correct choice is (b) using a parallel capacitor To EXPLAIN I WOULD say: Wattmeters are compensated for ERRORS caused by the inductance of pressure coil through the connection of a suitable parallel capacitor with multiplier resistance R. Fig illustrates that the total impedance of the pressure coil circuit Z2 EQUALS the total resistance of the pressure coil circuit namely R2.
