The opposition of a conductor to the flow of current is called
Correct answer: C. Resistance
- A. Conductance
- B. Inductance
- C. Resistance
- D. None of above
Explanation
Resistance is the opposition of a conductor to the flow of electric current. It is caused by collisions between electrons and atoms in the material of the conductor. Resistance is measured in ohms (Ω) and determines how much current will flow through a conductor for a given voltage.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
