The voltage-flux adjustment of a certain single phase 220 V induction watthour meter is altered so that the phase angle between the applied voltage and flux due to it 75° instead of this 90°. The error introduced in the reading of this meter when the current is 5 A at unity power factor is O -24.56 W O 37.48 W O 24.56 W O-37.48 W
