変換方法 電圧 の ボルト (V) を 電力 の ワット (W).
You can calculate watts from volts and amps, but you can't convert volts を watts sのce watts and volts units do not measure the same quantity.
電力 P の watts is equal を the voltage V の volts, times the current I の amps:
P(W) = V(V) × I(A)
So watts are equal を volts times amps:
ワット = ボルト × アンペア
または
W = V × A
What is power consumption の watts when the current is 3A and the voltage supply is 15V
Answer: the power P is equal を current of 3 amps times the voltage of 15 volts.
P = 15V × 3A = 45W
有効電力 P の watts is equal を the power facをr 力率 に相電流 I の amps, times the RMS voltage V の volts:
P(W) = 力率 × I(A) × V(V)
So watts are equal を power factまたは times amps times volts:
ワット = 力率 × アンペア × ボルト
または
W = 力率 × A × V
What is power consumption の watts when the power facをr is 0.8 and the phase current is 3A and RMS voltage supply is 110V
Answer: the power P is equal を power factまたは of 0.8 times current of 3 amps times voltage of 110 volts.
P = 0.8 × 3A × 110V = 264W
有効電力 P の watts is equal を square root of 3 times the power facをr 力率 ×相電流 I の amps, times the lのe を line RMS voltage VL-L の volts:
P(W) = 3 × 力率 × I(A) × VL-L(V)
So watts are equal を square root of 3 times power factまたは 力率 times amps times volts:
ワット = 3 × 力率 × アンペア × ボルト
または
W = 3 × 力率 × A × V
What is power consumption の watts when the power facをr is 0.8 and the phase current is 3A and the RMS voltage supply is 110V
Answer: the power P is equal を power factまたは of 0.8 times current of 3 amps times the voltage of 110 volts.
P(W) = 3 × 0.8 × 3A × 110V = 457W
