Ngendi kalkulator iki
Electrical power is the rate at which a device converts electrical energy, measured in watts. For a DC or purely resistive load it is simply voltage times current, P = V × I. For an AC load with a power factor below 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.
As a worked example, a device on a 120 V circuit drawing 10 A at unity power factor uses P = 120 × 10 = 1,200 W, which is 1.2 kW or about 1.61 hp. If instead it were a motor with a 0.8 power factor, the real power would fall to 120 × 10 × 0.8 = 960 W even though it still draws the same 10 A. Divide watts by 745.7 to convert to horsepower, or by 1,000 to get kilowatts.
The advanced usage fields turn power into running cost. Daily energy in kilowatt-hours is the power in kW multiplied by the hours used per day; multiply by your price per kWh for the daily cost and by 30 for a monthly estimate. A 1.2 kW load run 4 hours a day uses 4.8 kWh daily, about 144 kWh a month, which at $0.15/kWh is roughly $21.60 a month — the kind of figure that helps compare appliances, size a generator or budget a workshop.
Takon kang asring diajukake
Apa formulané tenaga listrik?
Ing basa Inggris, faktor daya dipérang dadi faktor daya 1 lan faktor daya 2. faktor daya 1 iku faktor daya kang dipérang dadi faktor daya 1 lan faktor daya 2.
Apa ana wong kang bisa ngrampungaké tugas iki?
Ing taun 2004, kutha iki ndunungi 1.757 jiwa lan duwé luas wewengkon 24,9 km².
Apa kang dadi sebabé?
Enerji saben dina iku daya (kW) × jam saben dina, ing kWh. Kakalikake karo 30 dina lan rega saben kWh kanggo ngitung biaya saben wulan.
Apa faktor daya lan kapan aku bisa ngganti?
Faktor daya iku pecahan saka daya nyata (V × I) kang gawé kerja nyata. Faktor iki 1 kanggo DC lan beban resistif kaya ta pemanas lan bohlam inframerah, nanging mudhun nganti kira-kira 0.7-0.9 kanggo motor lan akeh suplai elektronik, nyuda watt nyata.
Apa bedane antarané watt lan volt-amper?
Watt iku daya nyata (V × I × PF); volt-ampere iku daya nyata (V × I) tanpa faktor daya-korreksi. Kanggo beban resistif iku padha, nanging kanggo beban reaktif VA rating luwih dhuwur, ya iku sebabé generator lan UPS ratings diwènèhaké ing VA.
Kepiye aku bisa ngowahi watt dadi horsepower?
1200 W iku kira-kira 1.61 hp, lan motor 1 hp bisa ngasilaké 746 W daya mekanis-sakawiji (luwih listrik, nalika kerugian efisiensi wis diwènèhi).
