learn.whatIsHeading
Measures reactive vs. real power in AC circuits showing energy efficiency. Power factor <1 wastes electricity and increases utility costs.
सूत्र
Power factor = P ÷ S
- P
- P value — Variable used in the calculation
- S
- S value — Variable used in the calculation
चरण-दर-चरण मार्गदर्शिका
- 1Real power (P) in watts
- 2Apparent power (S) in VA (volts × amps)
- 3Power factor = P ÷ S
- 4Cosine of phase angle between voltage and current
- 5Range 0-1; closer to 1 is better
हल किए गए उदाहरण
इनपुट
P=1000W, S=1200VA
परिणाम
PF=0.833
सामान्य गलतियां जिनसे बचना है
- ✕Assuming residential power factor matters (most don't measure)
- ✕Not measuring true power with calibrated meters
अक्सर पूछे जाने वाले प्रश्न
How does low power factor increase costs?
Utilities charge penalty for PF <0.95; also increases I²R losses in distribution.
How do I improve power factor?
Add capacitors to offset inductive loads (motors, transformers) or use synchronous motors.
