Apparent power (S) = I x V
S = 9.615 x 240
  = 2.308 kVA
2.308 kVA is a much larger figure than 1.5 kW,
which indicates that the power factor in this
circuit is rather poor (substantially less than 1).
1.5 kW
pf =
     2.308 kVA
     1500
pf =
     2308
   = 0.65
Power factor (pf) = 0.65
(Cos¯¹ 0.65 = 49.46°)
