Answer:

7.33333

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)
