In household energy meters the flux of series magnet is in phase with current but the flux of shunt magnet lags the voltage by 88°. The reading of energy meters-A-will be correctB-will have a negative errorC-will have a positive errorD-may have positive or negative error-B-will have a negative error

Question

In household energy meters the flux of series magnet is in phase with current but the flux of shunt magnet lags the voltage by 88&deg;. The reading of energy meters-A-will be correctB-will have a negative errorC-will have a positive errorD-may have positive or negative error-B-will have a negative error

APTITUDE CRACK · Accepted Answer

B will have a negative error Since angle is less than 90&deg;, reading will be less. Therefore error is negative and correction is positive.
