The multimeter, also known as a volt ohm meter VOM (Measurements)

A #multimeter, also known as a multitester or a VOM (volt-ohm-milliammeter), is an electronic device used to measure different electrical quantities, such as #voltage, #current, and #resistance. It can also measure other parameters like #capacitance, #continuity, and #frequency.

The basic components of a multimeter include a display unit, a rotary switch, and two probes. The #rotary switch is used to select the type of measurement to be made, and the probes are used to connect the multimeter to the circuit being tested.

To measure voltage, the multimeter is connected across the two points where the voltage is to be measured. The voltage causes a current to flow through the multimeter, which is then displayed on the screen.

To measure current, the multimeter is placed in series with the circuit being tested. The current flows through the multimeter, and again, the value is displayed on the screen.

To measure resistance, the multimeter sends a small current through the circuit being tested and measures the resulting voltage drop. By knowing the amount of current sent and the voltage drop measured, the resistance of the circuit can be calculated and displayed on the screen.

The accuracy of a multimeter depends on its quality, the range of values it can measure, and the user's ability to use it properly. Multimeters are widely used in #electronics, electrical engineering, and various other fields where precise electrical #measurements are required.
