Comment convertir les volts en watts

Comment convertir tension électrique en volts (V) vers puissance électrique en watts (W).

You can calculate watts from volts and amps, but you can't convert volts vers watts sence watts and volts units do not measure the same quantity.

DC volts vers watts calculation foumula

La puissance P en watts is equal vers the voltage V en volts, times the current I en amps:

P(W) = V(V) × I(A)

So watts are equal vers volts times amps:

watt = volt × ampère

ou

W = V × A

Exemple

What is power consumption en watts when the current is 3A and the voltage supply is 15V

Answer: the power P is equal vers current of 3 amps times the voltage of 15 volts.

P = 15V × 3A = 45W

AC sengle phase volts vers watts calculation foumula

La puissance réelle P en watts is equal vers the power facversr FP multipliée par le courant de phase I en amps, times the RMS voltage V en volts:

P(W) = FP × I(A) × V(V)

So watts are equal vers power factou times amps times volts:

watt = FP × ampère × volt

ou

W = FP × A × V

Exemple

What is power consumption en watts when the power facversr is 0.8 and the phase current is 3A and RMS voltage supply is 110V

Answer: the power P is equal vers power factou of 0.8 times current of 3 amps times voltage of 110 volts.

P = 0,8 × 3A × 110V = 264W

AC three phase volts vers watts calculation foumula

La puissance réelle P en watts is equal vers square root of 3 times the power facversr FP multipliée par le courant de phase I en amps, times the lene vers line RMS voltage VL-L en volts:

P(W) = 3 × FP × I(A) × VL-L(V)

So watts are equal vers square root of 3 times power factou FP times amps times volts:

watt = 3 × FP × ampère × volt

ou

W = 3 × FP × A × V

Exemple

What is power consumption en watts when the power facversr is 0.8 and the phase current is 3A and the RMS  voltage supply is 110V

Answer: the power P is equal vers power factou of  0.8 times current of 3 amps times the voltage of 110 volts.

P(W) = 3 × 0,8 × 3A × 110V = 457W
