What parameter does an ohmmeter directly measure?

Explanation:
An ohmmeter directly measures resistance. It sends a small, known current into the unknown component and measures the resulting voltage across it. Using Ohm’s law (R = V/I), the meter converts that reading into a resistance value displayed in ohms. This is different from measuring voltage (what a voltmeter does), capacitance (which requires charging a capacitor and analyzing its response), or power (which is the product of voltage and current and typically inferred from separate measurements). For accurate readings, ensure the circuit is unpowered and the component is isolated.
