Power consumption calculator: calculates electric power / voltage / current / resistance.

Enter **2 values** to get the other values and press the

Voltage (V) calculation from current (I) and resistance (R):

*V*_{(V)} = I_{(A)} × *R*_{(Ω)}

Complex power (S) calculation from voltage (V) and current (I):

*P*_{(W)} = V_{(V)} × *I*_{(A)} = V^{ 2}_{(V)} / R_{(Ω)} = I
^{2}_{(A)} × *R*_{(Ω)}

Enter **2 magnitudes + 2 phase angles** to get the other values and press the *Calculate* button:

So The voltage V in volts (V) is eqaul to the current I in amps (A) times the impedance Z in ohms (Ω).

*V*_{(V)} = I_{(A)} × Z_{(Ω)} = *(|**I**|*×*|**Z*|) ∠
(*θ _{I}* + θ

So The complex power S in volt-amps (VA) is equal to the voltage V in volts (V) times the current I in amps (A).

*S*_{(VA)} = V_{(V)} × I_{(A)} = *(|**V**|*×*|**I*|) ∠
(*θ _{V}* - θ

So The real power P in watts (W) is equal to the voltage V in volts (V) times current I in amps (A) times the power factor (cos φ).

*P*_{(W)} = V_{(V)} × *I*_{(A)} × cos φ

So The reactive power Q in volt-amps reactive (VAR) is equal to the voltage V in volts (V) times the current I in amps (A) time the sine of the complex power phase angle (*φ*).

*Q*_{(VAR)} = V_{(V)} × *I*_{(A)} × sin φ

So The power factor (FP) is equal to the absolute value of the cosine of the complex power phase angle (*φ*).

*PF* = |cos φ|

Enter **2 values** to get the other values and press the *Calculate*button:

So The average power P in watts (W) is equal to the energy consumed E in joules (J) divided by time period Δ t in seconds (s).

*P*_{(W)} = E_{(J)} / Δ t_{(s)}
