Which circuit theorem dictates the condition under which maximum power is transferred from a source to a load?
Multiple Choice Options
- A
Norton
- B
Thevenin
- C✓ Correct Option
Maximum Power Theorem
- D
Ohm's Law
Detailed Technical Solution & Explanation
The Maximum Power Transfer Theorem states that maximum power is delivered from a linear source to a variable load when the load resistance equals the Thevenin internal resistance of the source (, or in AC circuits, ).
Option Analysis:
•
Option A (Norton): Incorrect. Norton's theorem gives an equivalent current source representation.
•
Option B (Thevenin): Incorrect. Thevenin's theorem gives an equivalent voltage source representation.
•
Option C (Maximum Power Theorem): Correct. Formulates the conditions for maximum power delivery to a load.
•
Option D (Ohm's Law): Incorrect. Relates voltage, current, and resistance in linear elements.
