Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The error is high due to hysteresis effect The meter does not respond to DC signals The error is high due to eddy current effect The meter is calibrated for AC and it’s error for DC would be high The error is high due to hysteresis effect The meter does not respond to DC signals The error is high due to eddy current effect The meter is calibrated for AC and it’s error for DC would be high ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation The resistance of a circuit is found by measuring current flowing and the power fed into the circuit. If the limiting errors in the measurement of power and current are ± 1.5% and ± 1.0% respectively, the limiting error in the measurement of resistance ± 1% ± 3.5% ± 2.5% ± 1.5% ± 1% ± 3.5% ± 2.5% ± 1.5% ANSWER DOWNLOAD EXAMIANS APP
