When measuring resistance, what should the multimeter be set to?

When measuring resistance, the multimeter should be set to the Ohm (Ω) mode. This setting is specifically designed for resistance measurements and allows the multimeter to send a small, known current through the resistor and measure the resulting voltage drop. Using Ohm's law, it calculates the resistance based on this current and voltage.

In this mode, the multimeter typically displays the resistance value directly in ohms, making it easy for the user to read and interpret. The other settings on the multimeter, such as voltage, current, or frequency, are intended for different types of measurements and would not provide accurate resistance readings. Therefore, using the Ohm mode ensures proper functionality and accurate measurements when assessing the resistance of a component or circuit.
