What setting on a digital multimeter is used to measure resistance?

The setting used on a digital multimeter to measure resistance is Ohms. Resistance is a measure of how much a device opposes the flow of electrical current, and it is expressed in ohms (Ω). This setting allows the user to determine the resistance of a circuit element or a component. When the multimeter is set to the ohm setting, it sends a small current through the component and measures how much that current is reduced by the component's resistance.

In contrast, the millivolt setting is used for measuring very small voltages, the milliamp setting is intended for measuring current in milliamps, and the voltage setting is used for measuring the potential difference across two points in a circuit. These other settings do not provide the capability to measure resistance, which is why only the Ohm setting is the correct choice.
