Part B
What is the equivalent conductance of the parallel connection?
Express your answer with the appropriate units.
Part C
What is the equivalent susceptance of the parallel connection?
Express your answer with the appropriate units.
Part D
If the parallel branches are excited from a sinusoidal current source where i= 10 cosωtA, what is the maximum amplitude of the current in the purely capacitive branch?
Express your answer with the appropriate units.
