Oh no, there’s been an error

Before we jump into the main topics lets understand what an R, L and C does in a circuit. Graphical Representation of Complex Numbers 4. The circuit along with the waveform is given below. A Inductor is also similar to capacitor, it also stores energy but is stored in form of magnetic field. Similarly we can also circulti the voltage across the capacitor at any given time and the current through the capacitor at any given time using the below formulas.

These are the three most used components in electronics circuit and you will find them in almost every application circuit.

The resonance property of a first order RLC circuit is discussed below.

9. Impedance and Phase Angle

Complex conjugates by phinah [Solved! Sign up for the free IntMath Newsletter. Then the capacitor charges up and Vr becomes zero and Vc becomes maximum. Presenting Z as a complex number in polar formwe have: The waveform is measured across the load bulb and is shown in yellow colour on the image above.


You can explore the effect of a resistor, circhiti and inductor on total impedance in an AC circuit. Let us calculate the time taken for our capacitor to charge up in the circuit.

RC, RL and RLC Circuit – Basic Principle and Circuit Explanations

A reader challenges me to define modulus of a complex number more carefully. Index problem by Rapelang [Solved!

Basic Operations in Complex Numbers 3. In trigonometric graphs, is phase angle the same as phase shift?

These circuit has the ability to provide a resonant frequency signal as shown in the below image. Got questions about this chapter?

Referring to Example 2 a above, suppose we have a current of 10 A in the circuit. Powers and Roots of Complex Numbers 8. A reader challenges my statement. The whole of electronics components can be slip into two broad categories, one being the Active components and the other as Passive components. A capacitor is an element which stores energy temporarily in form of electric field.

Where, V B is the battery voltage and I roc is the output current of the circuit. The inductor charges up quickly and hence a sudden voltage drop will be experienced by the resistive load R. We have calculated that the time taken for the capacitor to charge up will be 2. Explore impedance, current and voltage in an RLC circuit in the applet later on this page.


When these Resistor, Capacitor and Inductors are put together we can form circuits like RC, RL and RLC circuit which exhibits time and frequency dependent responses that will e useful in many AC applications as mentioned already. Similarly in a RL circuit we have to replace the Capacitor with an Inductor.

9. Impedance and Phase Angle

These three components together in different combinations will form rlf RC, RL and RLC circuits citcuiti they have many applications like from filtering circuits, Tube light chokes, multivibrators etc. A first order RC circuit will consist of only one Resistor and one Capacitor and we will analyse the same in this tutorial.

When the circuit is open, the voltage across the resistive load will be maximum and when the switch is closed the voltage from the battery is shared between the inductor and the resistive load.
