A parallel LRC circuit connected across a variable AC voltage source is drawn above. Find (in terms of and any quantities you define in terms of these such as or ):
a) The current in each element of the circuit. Don't forget the phase shifts (if any), and note that we are getting current from voltage - be careful!
b) Now find the current in the primary supply wire (as shown in
the figure above) with all terms, e.g. any required phase , and
the impedance defined and (at the end) numerically evaluated. You
will probably need to draw the appropriate phasor diagram to help you
figure this out unless you managed to memorize the entire circuit
chapter results.
