AC power calculator

  Impedance: Z = ∠ °  =   
  Current: I = ∠ °      
  Voltage: V = ∠ °      
  Power: S = ∠ °  =   
               

The instantaneous electrical AC power formula:

V(V) = I(A) × Z(Ω) = (|I|×|Z|) ∠ (θI + θZ)

Real power P in watts (W): P(W) = V(V) × I(A) × cos φ

power S in volt-amps (VA): S(VA) = V(V) × I(A) = (|V|×|I|) ∠(θV - θI)
