What is Voltmeter ?

Voltmeter Definition

A voltmeter is defined as an instrument that measures the voltage between two points in an electrical circuit.

Working Principle of Voltmeter

Voltmeters work by connecting in parallel to the circuit, using high resistance to measure voltage without significantly altering the circuit.

Types of Voltmeters

• Parmanent Magnet Moving coil (PMMC) Voltmeter.

• Moving Iron (MI) Voltmeter.

• Electro Dynamometer Type Voltmeter.

• Rectifier Type Voltmeter

• Induction Type Voltmeter.

• Electrostatic Type Voltmeter.

• Digital Voltmeter (DVM).

PMMC Voltmeter

Uses a permanent magnet and moving coil to measure DC voltage with high accuracy and low power consumption.

Digital Voltmeter (DVM)

Measures voltage digitally, providing accurate, fast readings and eliminating parallax error.
