Principle of operation of voltmeter
WebPrinciple of Operation Electrostatic voltmeter utilizes the attraction force between two charged surfaces to create a deflection of a pointer directly calibrated in volts. Since the attraction force is the same regardless of the polarity of the charged surfaces (as long as the charge is opposite), the electrostatic voltmeter can measure both direct current and … WebPMMC, moving iron, electrodynamometer type, true RMS, Q-meter and sampling voltmeter.
