The unit for measuring electrical resistance is called what?

• A. Amperes
• B. Volts
• C. Ohms
• D. Watt-hours

Answer: (C)

The unit for measuring electrical resistance is called Ohms. This measurement, symbolized by the Greek letter Omega (Ω), quantifies how much a material opposes the flow of electric current. Understanding resistance is essential for diagnosing electrical issues in automotive systems, as it helps to assess components like resistors, circuits, and wiring. Amperes measure electric current, indicating the flow of electric charge, while Volts measure electric potential difference, essentially representing the force that pushes the current through the resistance. Watt-hours, on the other hand, is a measure of energy consumption over time, not directly related to resistance. Thus, Ohms is the specific unit that pertains to resistance in an electrical context.
