AC2 Fundamentals Unit 1 – RLC Circuits
UNIT 1 – RLC CIRCUITS
UNIT OBJECTIVE
At the completion of this unit, you will be able to analyze series and parallel RLC circuits by
using calculations and measurements.
UNIT FUNDAMENTALS
Many electronics circuits are made up of resistors (R), inductors (L), and capacitors (C). Such
networks are referred to as RLC circuits. There are many ways that resistors, inductors, and
capacitors can be connected.
One way to connect these three components is in series.
Another way to arrange these three components is in parallel.
More complex RLC circuits are made up of combinations of series and parallel RLC circuits.
Varying the frequency of the applied voltage (VGEN) causes both the inductive (XL) and
capacitive (XC) reactances to change which results in the total circuit current (IT) changing.
