Atik sa a

a DC load with a power factor above 1 — motors, transformers and other inductive loads — the real power that does useful work is P = V × I × PF, while the product V × I alone gives the larger apparent power in volt-amperes. This calculator reports the power in watts, kilowatts and mechanical horsepower, using 1 hp = 745.7 W. If instead it were a motor with a power factor of 0.8, the real power would fall to 120 × 10 × 0.8 = 1,200 W, which is about 1.61 hp. Multiply by your price per kWh for the daily cost and by 30 for the monthly estimate.The advanced usage fields turn power into running cost. Daily energy in kilowatt-hoursAs

Kesyon ki poze souvan

Ki sa ki se fòmil la pouvwa elektrik?

Pou DC oswa yon chaj rezistif faktè pouvwa a se 1, se konsa pouvwa a se jis tanperati fwa koule a.

Ki kantite watt nan yon pouvwa?

Yon mekanis horsepower egal a 745.7 wat, se konsa yon 1492 W chaj se sou 2 hp. Divizyon wat pa 745.7 pou konvèti.

Ki jan pri a ap travay?

Enèji chak jou se pouvwa (kW) × èdtan chak jou, nan kWh. Multiplie pa 30 jou ak pri ou pou chak kWh pou estime pri chak mwa.

Ki sa ki se faktè pouvwa ak lè mwen chanje li?

Faktori pouvwa se fraksyon nan pouvwa aparental (V × I) ki fè travay reyèl. Li se 1 pou DC ak chaj rezistif tankou chofaj ak ampoules incandescent, men tonbe a apeprè 0.7-0.9 pou motè ak anpil ekipman elektwonik, diminye wats reyèl.

Ki diferans ki genyen ant wat ak volt-ampères?

Watts se pouvwa reyèl (V × I × PF); volt-ampères se pouvwa apparent (V × I) san okenn koreksyon pouvwa-faktè. Pou chaj rezistif yo egal, men pou chaj reaktif VA rating se pi wo, ki se poukisa jeneratè ak UPS ratings yo bay nan VA.

Kijan pou mwen konvèti wats pou horsepower?

Divide watt pa 745.7.Se konsa, 1,200 W se sou 1.61 hp, ak yon 1 hp motè tire sou 746 W nan pouvwa mekanik-ekwivalent (plis elektrikman, yon fwa pèt efisians yo enkli).
