Measurement and Instrumentation Two voltmeters have the same range 0-400V. The internal impedance are 30,000 Ohms and 20,000 Ohms. If they are connected in series and 600V be applied across them, the readings are 360V and 240V One of the meters out of the range and other 100V 300V each 400V and 200V 360V and 240V One of the meters out of the range and other 100V 300V each 400V and 200V ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The error is high due to hysteresis effect 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 meter does not respond to DC signals The error is high due to hysteresis effect 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 meter does not respond to DC signals ANSWER DOWNLOAD EXAMIANS APP
