A balanced Y-connected load with (Z_{Y}=100-j 20) (Omega) per phase is connected in parallel with a balanced

Question:

A balanced Y-connected load with \(Z_{Y}=100-j 20\) \(\Omega\) per phase is connected in parallel with a balanced \(\Delta\) connected load with \(Z_{\Delta}=120+j 500 \Omega\) per phase.

(a) Find the phase impedance of an equivalent \(Y\) connected load and an equivalent \(\Delta\)-connected load. Use MATLAB.

(b) Which equivalent impedance load has the best power factor?
