What does an ohmmeter help determine?

• A. The color of insulation
• B. If a wire or component conducts electricity well or not
• C. The weather conditions
• D. The circuit's power rating

Answer: (B)

An ohmmeter measures electrical resistance, which shows how easily current can flow through a path. By applying a small current and reading the voltage drop, the meter computes resistance. A low resistance means the wire or component conducts electricity well; a high or infinite resistance means it does not conduct well or is open. So the meter is used to check continuity and identify good conductors versus faulty or broken paths. It doesn’t tell you insulation color, weather conditions, or a circuit’s power rating.
