# Physics Tutorial 16.15 - Introduction to RLC Circuits

There are 4 lessons in this physics tutorial covering Introduction to RLC Circuits. The tutorial starts with an introduction to Introduction to RLC Circuits and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Introduction to RLC Circuits. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• What is a RLC circuit?
• Why oscillations in a RLC circuit are damped?
• What is the equation of oscillations in a RLC circuit?
• What is angular frequency of damped oscillations? How does it differ from the angular frequency of undamped oscillations?
• How to find the energy in a damped RLC circuits at any instant?
• What are forced oscillations? What do they cause in an electric circuit?
• How to calculate the AC current and emf caused by forced oscillations in a circuit at any instant?
• How to cope with AC circuits containing a single resistor/capacitor/inductor?
• What are phasor diagrams? Why do we use them?

## Introduction

In the previous tutorial, we have discussed about LC circuits. What happens if we add a resistor in this circuit? Recall what we said in the previous tutorial about the resistance of LC circuits and how it affects the energy distribution in the circuit.

Do you think capacitors have resistance? What about inductors? Recall how an inductor behaves after a long time of circuit operation. What can you say about the resistance of inductor at the beginning of process?

Now, let's explain these questions by considering the most inclusive type of circuit - the RLC circuit. For simplicity, here we will consider only the series RLC circuit.
