Malunga nale Calculator
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.
Imibuzo ebuza rhoqo
Yintoni ifomula yombane?
Umandla okweli hlabathi ngeewatts yiP = V × I × PF. Kwi-DC okanye umthwalo omelanayo umandla owenzayo ngu-1, ngoko amandla alula umbane ojikelezayo uphindaphindwa ngoku.
Ingaba zininzi i-watts kwi-horsepower?
Imoto enye yenjini ilingana ne-745.7 watts, ngoko umthwalo we-1492 W umalunga ne-2 hp. Yahlula i-watts nge-745.7 ukutshintsha.
Ixabiso eliqhubayo lisebenza njani?
Umbane wosuku ngalunye unamandla (kW) × iiyure ngosuku, nge-kWh. Ukuphindaphinda ngeentsuku ezi-30 kunye nexabiso lakho nge-kWh ukuqikelela iindleko zenyanga.
Yintoni i-power factor yaye ndiyitshintsha nini?
Uxinzelelo lomandla luyinxalenye yomandla abonakalayo (V × I) eyenza umsebenzi olungileyo. I-1 ye-DC kunye nobunzima obuchaphazelayo njengezifudumeza kunye neebhobho ezikhanyayo, kodwa ihla ukuya kuma-0.7-0.9 kumamoto kunye nezixhobo ezininzi ze-elektroniki, ikunciphisa i-watts elungileyo.
Yintoni utshintsho phakathi kwee-watts nevolthi-ampere?
Iiwatts zinamandla asebenzayo (V × I × PF); iivolthi-ampere zinamandla abonakalayo (V × I) ngaphandle kokulungisa isizathu sokusebenza. Kumacala omabini obunzima balingana, kodwa kumacala omabini obunzima obunoxinzelelo oluphezulu umgangatho weVA uphezulu, oko kukuthi, igenerator ne UPS zinikezelwa nge VA.
Ndiyiguqula njani i-watts ibe yi-horsepower?
Yahlula i-watts nge-745.7. Ngoko ke i-1,200 W imalunga ne-1.61 hp, kwaye i-1 hp motor itsala malunga ne-746 W ye-mechanical-elinganayo (ingakumbi nge-electric, xa ukulimala okusebenzayo kuquka).
API — sebenzisa le calculator ukusuka kwikhowudi
Nceda le khadi lemali njengendawo esemva ye-JSON ekhululekileyo - akukho qhosha lifunekayo. Thumela amaxabiso endawo ezantsi njengeparameter yombuzo okanye i-JSON. Nantoni na oyenzayo isebenzisa okungagqibekanga okufanayo eli phepha ligqityiwe ngaphambili; iparameter engaziwayo yi 400, ayikho i zero ekhululekileyo. Funda i-API epheleleyo →
