Which instrument is used to measure electrical resistance?

Explanation:
To measure electrical resistance, you use a device that applies a small, known current and reads the resulting voltage (or, vice versa) to determine the value in ohms. The ohmmeter is designed for this purpose and will display the resistance directly when the circuit is de-energized. This makes it the go-to instrument for checking resistor values or continuity in a lead or component. A voltmeter measures voltage, not resistance, and an ammeter measures current. A multimeter can measure resistance as one of its functions, but the instrument specifically built for resistance measurement is the ohmmeter.
