Resistance in an electrical circuit is measured in units called _____.

• A. Volts
• B. Amperes
• C. Ohms
• D. Watts

Answer: (C)

Resistance in an electrical circuit is measured in units called ohms. The unit of ohm is symbolized by the Greek letter omega (Ω). Ohm’s Law, which is fundamental to understanding electrical circuits, states that the voltage (in volts) across a conductor between two points is directly proportional to the current (in amperes) flowing through it, provided the temperature remains constant. The resistance (in ohms) quantifies how much the conductor opposes the flow of electric current. In practical terms, understanding resistance is crucial for designing circuits, ensuring safety, and optimizing performance in electrical systems. The other units mentioned relate to different aspects of electrical measurements: volts measure electrical potential, amperes measure current flow, and watts measure power. Each of these has its specific function, but when it comes to resistance specifically, ohms is the correct unit of measurement.
