Three branches having impedances of 3 + /4 O, 16 - /12 ft, and - / 4 ft, respectively, are connected in parallel. What are the equivalent (a) admittance, (b) conductance, and (c) susceptance of the parallel connection in millisiemens? (d) If the parallel
branches are excited from a sinusoidal current source where i = 8 cos w/ A, what is the maximum amplitude of the current in the purely capacitive branch?
