Voltmeters and Multimeters Articles: DC Meter: The most commonly used dc meter is based on the fundamental principle of the motor. The motor action is produced by the flow of…
Digital Voltmeters Articles: Digital Voltmeters Features and Characteristics: Digital Voltmeters Features and Characteristics which includes measuring instruments that convert analog voltage signals into a digital or numeric readout. This digital…
Peak Reading Voltmeter Circuit: Sometimes it is enough if the Peak Reading Voltmeter Circuit of an impulse voltage wave is measured; its waveshape might already be known or fixed by…
Peak Reading AC Voltmeter Circuit: Peak Reading AC Voltmeter Circuit : When a capacitor is connected to a sinusoidal voltage source, the charging current where V is the rms value…
Electrostatic Voltmeters: In Electrostatic Voltmeters fields, the attractive force between the electrodes of a parallel plate capacitor is given by where, V = applied voltage between plates, C = capacitance…
Series Capacitance Voltmeter: To avoid the drawbacks pointed out earlier, a Series Capacitance Voltmeter is used instead of a resistor for a.c. high voltage measurements. The schematic diagram is shown…
Series Impedance Voltmeter: For power frequency a.c. measurements the Series Impedance Voltmeter may be a pure resistance or a reactance. Since resistances involve power losses, often a capacitor is preferred…
Generating Voltmeter Principle and Construction: High voltage measuring devices employ generating principle when source loading is prohibited (as with Van de Graaff generators, etc.) or when direct connection to the…
