    Explanation:

    The voltage V in volts (V) is equal to the current I in amps (A) times the impedance Z in ohms (Ω):

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

    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|) ∠ (θV - θI)
