Hi All,
Referring to Question 9 of the worksheet titled "Series and parallel AC circuits" (http://www.allaboutcircuits.com/worksheets/ac_s_p.html),
I get the phase angle at -42.08 by doing the following steps:
1.) Calculated Xc = 0 - j1354.51Ω
2.) Calculated the phase difference at -42.08° using θ = arctan Xc/R
The worksheet answer is -47.9°, which seems like it's a complimentary
angle to -42.08°
Could anybody please help me understand why the phase difference is
not -42.08° as calculated in step 2 above?
Sincerely,
tjterblanche
