WATTS = VOLTS x AMPS
To solve for unknown watts - volts x amps = watts 120v x 10a = ?w or 1,200 watts
To solve for unknown amps - watts / volts = amps 1,500w / 120v = ?a or 12.5 amps
To solve for unknown volts - watts / amps = volts 1,200w / 5a = ?v or 240volts
KiloVoltAmps x Power Factor = Kilowatts
Assuming 60hz North American System
To solve for unknown Kw: KVA x Power Factor = Kw 20Kva x .8 = ? Kw or 16 Kw
To solve for unknown KVA: KW x 1.25 (reverse of .8) = KVA 36Kw x 1.25 = ?Kva or 45Kva |
