Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It loads the circuit to maximum extent. It uses centre zero galvanometer instead of voltmeter. It does not load the circuit at all. It loads the circuit moderately. It loads the circuit to maximum extent.

Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The meter does not respond to DC signals The meter is calibrated for AC and it’s error for DC would be high The error is high due to eddy current effect The error is high due to hysteresis effect The meter does not respond to DC signals The meter is calibrated for AC and it’s error for DC would be high The error is high due to eddy current effect The error is high due to hysteresis effect ANSWER DOWNLOAD EXAMIANS APP
