The symbol for ohm represents which electrical property?

The symbol for ohm represents which electrical property?

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

Answer: (D)

The symbol for ohm is the unit for resistance. It names how strongly a component or material resists the flow of electric current. In the relationship V = I × R (Ohm’s law), resistance links voltage and current, so the Ω symbol specifically denotes resistance. Current is measured in amperes (A), not the ohm; voltage is measured in volts (V); conductance, measured in siemens (S), is the reciprocal of resistance. Since the symbol Ω represents resistance, it’s the correct choice.
