In any practical AC circuit, which relationship among power components is always true?
In any practical AC circuit, which relationship among power components is always true?
Multiple Choice Options
- A✓ Correct Option
apparent power is more than actual power
- B
reactive power is more than apparent power
- C
actual power is more than reactive power
- D
reactive power is more than actual power
Detailed Technical Solution & Explanation
In AC circuits, apparent power ( in VA) forms the hypotenuse of the power triangle, where actual (active) power is and reactive power is . Because power factor , apparent power is always greater than or equal to actual power .
Option Analysis:
•
Option A (apparent power is more than actual power): Correct. Since , is always satisfied for any power factor .
•
Option B (reactive power is more than apparent ...): Incorrect. ; reactive power cannot exceed the hypotenuse .
•
Option C (actual power is more than reactive power): Incorrect. In highly inductive or capacitive circuits (low power factor), reactive power can exceed active power.
•
Option D (reactive power is more than actual power): Incorrect. Not universally true.
