Cómo convertir voltaje eléctrico en voltios (V) a potencia eléctrica en vatios (W).
You can calculate watts from volts and amps, but you can't convert volts a watts sence watts and volts units do not measure the same quantity.
La potencia P en watts is equal a the voltage V en volts, times the current I en amps:
P(W) = V(V) × I(A)
So watts are equal a volts times amps:
vatio = voltio × amperio
o
W = V × A
What is power consumption en watts when the current is 3A and the voltage supply is 15V
Answer: the power P is equal a current of 3 amps times the voltage of 15 volts.
P = 15V × 3A = 45W
La potencia real P en watts is equal a the power facar FP multiplicado po la coriente de fase I en amps, times the RMS voltage V en volts:
P(W) = FP × I(A) × V(V)
So watts are equal a power facto times amps times volts:
vatio = FP × amperio × voltio
o
W = FP × A × V
What is power consumption en watts when the power facar is 0.8 and the phase current is 3A and RMS voltage supply is 110V
Answer: the power P is equal a power facto of 0.8 times current of 3 amps times voltage of 110 volts.
P = 0.8 × 3A × 110V = 264W
La potencia real P en watts is equal a square root of 3 times the power facar FP multiplicada po la corriente de fase I en amps, times the lene a line RMS voltage VL-L en volts:
P(W) = 3 × FP × I(A) × VL-L(V)
So watts are equal a square root of 3 times power facto FP times amps times volts:
vatio = 3 × FP × amperio × voltio
o
W = 3 × FP × A × V
What is power consumption en watts when the power facar is 0.8 and the phase current is 3A and the RMS voltage supply is 110V
Answer: the power P is equal a power facto of 0.8 times current of 3 amps times the voltage of 110 volts.
P(W) = 3 × 0.8 × 3A × 110V = 457W
