Voltmeter is a type of meter that is used to measure electrical pressure. By using this meter, we can measure difference between electrical pressure.
we can check the supply voltage of the circuit. Difference voltmeters are used for AC and DC.
A voltmeter is worked paralell with circuit. Range of these meters is 0 to 250/500 volts. But for the range of DC voltmeter which started from zero (0) to 30 volts.
