In electrical systems, what does a VOM multimeter typically measure?

A VOM (Volt-Ohm-Milliammeter) multimeter is designed to measure multiple electrical parameters, which primarily include voltage, current, and resistance. This multifunctionality is one of the key advantages of a multimeter, making it a versatile tool for electricians and technicians.

When measuring voltage, the multimeter functions to determine the potential difference between two points in an electrical circuit. This is essential for checking the integrity of circuits, power supplies, and outlets.

In terms of current measurement, the VOM can assess the flow of electric charge in a circuit, which is crucial for ensuring that devices are operating within their specified limits and for troubleshooting issues related to current flow.

Additionally, measuring resistance with a multimeter allows for checking the continuity of circuits and the condition of components, such as resistors and connections, to identify any faults or unexpected behavior in the system.

The ability to measure these three key parameters (voltage, current, and resistance) makes the multimeter an invaluable tool in both practical applications and theoretical understanding of electrical systems.
