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 400V and 200V 300V each One of the meters out of the range and other 100V 360V and 240V 400V and 200V 300V each One of the meters out of the range and other 100V 360V and 240V ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It does not load the circuit at all. It loads the circuit to maximum extent. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter. It does not load the circuit at all.
