Series Capacitance Voltmeter Function
A series capacitance voltmeter utilizes capacitors in series within its circuit. The fundamental property of capacitors is that they block the flow of direct current (DC) while allowing alternating current (AC) to pass through.
Measuring AC Voltage
Because a series capacitance voltmeter incorporates capacitors, it effectively blocks any DC component from reaching the measuring instrument. This ensures that the voltmeter only responds to and measures the AC voltage component present in the circuit.
Reasoning for Measurement Type
- DC Voltage: Capacitors act as open circuits to DC, preventing its passage. Thus, a series capacitance voltmeter cannot measure DC voltage.
- AC Voltage: Capacitors allow AC voltage to pass, with the impedance depending on the frequency and capacitance value. This enables the voltmeter to measure the AC voltage accurately.
- Currents: Voltmeters, by design, measure voltage differences, not current.
Therefore, a series capacitance voltmeter is specifically designed to measure AC voltage.
