In electrical terminology, what does 'ohm' measure?

• A. Voltage
• B. Current
• C. Resistance
• D. Power

Answer: (C)

Ohm is a unit of measurement that quantifies resistance in an electrical circuit. When you consider Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R), it becomes clear that resistance is the key variable being measured by ohms. Resistance indicates how much a conductor opposes the flow of electric current. For example, a higher resistance means that less current will flow for a given voltage. In practical terms, ohms help engineers and electricians design circuits and choose appropriate components by specifying how much resistance must be overcome for current to flow effectively.
