What is voltmeter multiplier?

A voltmeter multiplier is a resistive component used in voltmeter circuits to extend the range of voltage measurements. It operates by increasing the input resistance of the voltmeter, allowing it to measure higher voltages without drawing significant current from the circuit being tested. Typically, it consists of a series resistor connected to the voltmeter, which limits the current and protects the measuring device from high voltage. This design ensures accurate readings across a broader voltage range.
