Measurement and Instrumentation For power measurement of three phase circuit by two wattmeter method, when the value of power factor is less than 0.5 lagging Pressure coil of the wattmeter will become ineffective. One of the wattmeters will read zero One of the wattmeter connections will have to be reversed Both give the same readings Pressure coil of the wattmeter will become ineffective. One of the wattmeters will read zero One of the wattmeter connections will have to be reversed Both give the same readings ANSWER DOWNLOAD EXAMIANS APP
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 300V each One of the meters out of the range and other 100V 400V and 200V 360V and 240V 300V each One of the meters out of the range and other 100V 400V and 200V 360V and 240V ANSWER DOWNLOAD EXAMIANS APP

Measurement and Instrumentation A DC potentiometer is the best means available for the measurement of DC voltage because It is based on null balance technique. None of above. It is possible to standardize before a measurement is undertaken. The precision in measurment is independent of the type of the defector used. It is based on null balance technique. None of above.
