Measurement and Instrumentation If two 300V full scale voltmeters V1 and V2 having sensitivities of 100 kOhm/V and 150 kOhm/V are connected in series to measure 500V then V1 = 250V and V2 = 250V. V1 = 200V and V2 = 300V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. V1 = 250V and V2 = 250V. V1 = 200V and V2 = 300V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The error is high due to eddy current 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 hysteresis effect The error is high due to eddy current 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 hysteresis effect ANSWER DOWNLOAD EXAMIANS APP
