Q. Explain working of Voltmeter?

In order tomeasure the potential difference between two terminals or nodes of a circuit, a voltmeter is connected across these two points. A practical voltmeter can usually be modeled as a parallel combination of an ideal voltmeter (through which no current flows) and a shunt resistance RV,as shown in Figure. The internal resistance RV of an ideal voltmeter is infinite, while its value in practice is of the order of several million ohms. There are what are known as dc voltmeters and ac voltmeters. An ac voltmeter usually measures the rms value of the time-varying voltage.
