Can you please have a look at Q3 part (iii) in the attached file.
When asked to calculate the current, do i use Phasor solution or Eulers notation. I have used both methods but got different answers!
Phasor solution:
Impedance Z = (R^2 + XL^2 + Xc^2)^0.5
So: I = V/Z = 150/116.45 = 1.29A
Eulers notation:
Z = 25 + j94.25 - j63.66 = 25 + j30.59
So: I = 150/(25 + j30.59) = (3750 - j4588.5)/1560.75 = 3.80A
Any help is greatly appreciated.
