A multimeter is an electrical measuring instrument used to measure voltage, current, and resistance in electrical and electronic circuits. It may be analog or digital and is commonly used by electricians, technicians, and engineers for testing and troubleshooting electrical systems. The device includes a display or pointer, selector switch, and test probes.
Operation:
The multimeter operates by connecting its probes to the circuit or component being tested. The user selects the required measurement function and range, such as voltage, current, or resistance. The instrument then measures the electrical value and displays the result on the screen or scale, helping users detect faults, check continuity, and test electrical components accurately.
