The Ohm is the unit used to measure which electrical property?

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

Answer: (C)

Resistance is a measure of how much a component resists the flow of electrical current. The ohm is the unit that quantifies this property, defined as one volt per ampere. In practical terms, it tells you how much current will flow for a given voltage: I = V / R. For example, if you apply 6 volts across a 3-ohm resistor, the current would be 2 amperes. Voltage is measured in volts, current in amperes, and power in watts, while the ohm specifically describes resistance.
