(a) Since I = V/Z, where Z is the impedance of the circuit and given by

Now

Put in the above formula,

Now put this value of Z in the equation for the current, I = 230/12.2 = 18.85 Amp

(b) Phase angle

(lagging behind)

(c) Power factor is given by cosϕ

(d) Power consumed = VIcosϕ =230 × 18.85 × 0.573 = 2484.2 Watt
