se the multimeter to measure electricity. It can check voltage (V), current (A), and resistance (Ω) in a circuit. This makes it very useful for testing and fixing electrical problems.

There are two types of multimeters:

An analog multimeter shows readings with a moving needle.
A digital multimeter shows the values on a screen.
A multimeter has two wires called probes:

The black probe connects to the COM (common) port and is usually the negative or ground wire.
The red probe connects to different ports based on what you are measuring (like VΩmA for voltage, resistance, or low current; or a separate 10A port for higher current).
You can turn a rotating dial on the multimeter to choose what you want to measure:

V for voltage (DC or AC)
A for current
Ω for resistance
Some multimeters also measure things like continuity (with a beep sound), diodes, temperature, or capacitance.
