The maximum power transfer theorem states that maximum power is delivered to the load when
Correct answer: D. The load resistance is equal to the source resistance
- A. The load resistance is half of the source resistance
- B. The load resistance is zero
- C. The load resistance is double the source resistance
- D. The load resistance is equal to the source resistance
Explanation
When the load resistance matches the source resistance, the system operates at optimal efficiency, ensuring that the maximum possible power is transferred to the load.

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.
