Power factor a ennu 1.0 kyerɛ sɛ afiri no twetwe current pii sen sɛnea Watt/Volt akontaabu a ɛnyɛ den no kyerɛ. Sɛ wopɛ sɛ wohu nokware amp draw wɔ AC nhyehyɛe ahorow a ɛwɔ tumi factor a enye: amps=watts ÷ (Volts × Power Factor). Motors taa nya ahoɔden factors bɛyɛ 0.7-0.85.

So wɔpia amps no anaasɛ wɔtwe fa ɔmansin bi mu?

Current yɛ "drawn" anaa "pulled" denam adesoa no so, ɛnyɛ nea source no na ɛpia no. Fibea no ma voltage (electrical pressure), na load no resistance na ɛkyerɛ sɛnea current no sen. Eyi nti na asɛmfua no yɛ "amp draw" mmom sen "amp push." Ɛsɛ sɛ fibea no tumi de current a wɔhwehwɛ no ma, nanso adesoa no na ɛhwɛ dodow a ɛsen ankasa so.

Battery-Powered applications no nya mfaso titiriw fi amp draw a wɔte ase no mu, efisɛ mprempren a wɔde di dwuma no kyerɛ runtime tẽẽ wɔ charges ntam.
