Ohms is the unit for what electrical property?

Ohms is the unit for what electrical property?

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

Answer: (C)

The unit ohm measures resistance—the opposition a material or component presents to electric current. Ohm’s law links these quantities: V = I R, so resistance is R = V / I. That means the ohm is volts per ampere, which is the standard unit for resistance. Voltage is measured in volts, current in amperes, and power in watts, so the ohm specifically identifies the resistance property.
