Calculate S, complex power of a load (in rectangular form), given the following data:
magnitude of S = 600 VA; Q = 450 VAR (inductive). See attached file for full problem description.
Please see the attached file.
Total power of a reactive load can be expressed as :
S = VI cosθ + j VI sinθ where V and I are rms values of voltage and current and θ is the phase angle. ............(1)
In (1) VI cosθ is known as the active ...
The problem has been solved first explaining the fundamental principles involved.
