Resistance is measured using a(n) ______.

Explanation:
To determine resistance, you need an instrument that applies a known stimulus and translates the response into ohms. An ohmmeter is designed for this purpose: it injects a small current from its internal battery through the unknown resistance and measures the resulting current or voltage, then converts that information into a resistance reading. This is why the meter shows a value in ohms directly. Other instruments have different primary roles. A voltmeter measures potential difference between two points and is connected in parallel, a ammeter measures current by being placed in series and is designed to have very low resistance so it doesn’t affect the circuit, and a galvanometer is the sensitive current-detecting element used inside some meters but not a standalone device for finding resistance. Thus, the correct device for measuring resistance is the ohmmeter. Remember to measure resistance with power removed from the circuit to get accurate results.
