## How Does Multimeter Work?

1. How does a multimeter measure voltage?

2. How does a multimeter measure resistance?

3. How does a multimeter measure current?

## Explanation.

1. A multimeter measures voltage by connecting its probes to the circuit or component being tested. Voltage is the difference in electrical potential between two points in a circuit, and the multimeter measures this difference in volts. The multimeter's display will show the voltage reading in either AC (alternating current) or DC (direct current) voltage, depending on the setting chosen.

2. To measure resistance, the multimeter sends a small known current through the component being tested and measures the voltage drop across it. The resistance is then calculated using Ohm's Law: resistance = voltage / current. The multimeter displays the resistance in ohms, indicating how much the component resists the flow of current.

3. When measuring current, the multimeter is placed in series with the circuit being tested. The multimeter acts as a conductor, allowing current to flow through it and measuring the amount of current passing through. The multimeter displays the current reading in either amperes (A) or milliamperes (mA), depending on the setting chosen. It is important to select the appropriate current range on the multimeter to prevent damage to the device.
