Q

What is an ohmmeter used to measure?

🔍 Key Concepts

• Ohm’s Law (E = I × R) and the relationship between voltage, current, and resistance • Common electrical test instruments: voltmeter, ammeter, ohmmeter • What part of a circuit is checked when looking for a broken wire or bad connection

💭 Think About

• Think about which electrical quantity is described in ohms and appears as R in Ohm’s Law. • Ask yourself: when a technician checks if a wire or component is open or shorted, which meter setting is normally used? • Match each common meter type (voltmeter, ammeter, ohmmeter, wattmeter) with what it measures and compare to the choices.

✅ Before You Answer

• Identify which choice corresponds to the quantity measured in ohms (Ω). • Exclude any options that are usually measured in volts (V), amperes (A), or watts (W). • Confirm you know the basic function of a multimeter’s resistance setting before deciding.
