Homework Answers
here,
in an AC circuit,
the current and voltage do not peak at the same time
the fraction of a period difference between the peaks expressed in degrees is said to be the phase difference.
The phase is negative for a capacitive circuit since the current leads the voltage by 90 degree
the current a) leads the voltage by 90 degrees
