Parallel AC Circuit Analysis
The following are example problems calculated for parallel AC circuits.
They include parallel
RL, LC, and RLC circuits.
The equivalent series circuit will be shown for all three
An RC parallel combination circuit is not shown, but using the process for the
RL circuit, you should be able to calculate an example of your own.
The procedures shown are
for calculating ZT.
You should be able to calculate total current, individual component currents,
component powers, and the apparent power(PA) for the circuit.
Practice putting all of your
answers in polar and rectangular form and use the branch currents to verify Kirchoff’s current
law for total current in the circuit. Make sure you include your angles with the current values you
calculate and put proper units on circuit parameters.
Find ZT for the circuit shown. (RL analysis)
