It is also very commonly used as damper circuits in analog applications. Initially when the switch is open maximum voltage 12V appears across the resistive light bulb load Vr and the voltage across the capacitor will be zero. Before we start with each topic let us understand how a Resistor, Capacitor and an Inductor behave in an electronic circuit. The circuit forms an Oscillator circuit which is very commonly used in Radio receivers and televisions. In this case, we have: The Light bulb is assumed to act as a pure resistive load and the resistance of the bulb is set to a known value of ohms.
Few of them are listed below. The value of t is the time in seconds at which the voltage or current value of the Inductor has to be calculated.
Products and Quotients of Complex Numbers Graphical explanation of multiplying and dividing complex numbers 7. Complex numbers in math class. Similarly we can also calculate the voltage across the capacitor at any given time and the current through the capacitor at any given time using the below formulas.
A resistor is an element that dissipates energy mostly in form of heat. Let us analyse the wave form in the above image to understand what is actual happening in the circuit is. The time taken for Vr to reach from 0V to 12V is equal to the time taken for the capacitor to charge from 0V to maximum voltage. When the switch is closed the voltage across the resistor will drop to zero and then as the capacitor charges the voltage will reach back to maximum as shown in the graph.

Where, V B is the battery voltage and I o is the output current of the circuit. Get Our Weekly Newsletter! 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.
So in this tutorial we will learn the basic of these circuits, the theory behind them and how to use them in our circuits. They charge in one direction and discharge in opposite direction. This website uses cookies to improve your experience while you navigate through the website.

The RC circuit Resistor Capacitor Circuit will consist of a Capacitor and a Resistor connected either in series or parallel to a voltage or current source.
These types of circuits are also called as RC filters or RC networks since they are most commonly used in filtering applications. An RC circuit can be used to make some crude filters like low-pass, high-pass and Band-Pass filters. A first order RC circuit will consist of only one Resistor and one Capacitor and we will analyse the same in this tutorial.
To understand the RC circuit let us create a Basic circuit on proteus and connect the load across the scope to analyse how it behaves. The circuit along with the waveform is given below. We have connected a load light bulb of known resistance 1k Ohms in series with a capacitor of uF to form a RC circuit. The circuit is powered by a 12V battery and a switch is used to close and open the circuit. The waveform is measured across the load bulb and is shown in yellow colour on the image above.
Initially when the switch is open maximum voltage 12V appears across the resistive light bulb load Vr and the voltage across the capacitor will be zero. When the switch is closed the voltage across the resistor will drop to zero and then as the capacitor charges the voltage will reach back to maximum as shown in the graph.
Let us calculate the time taken for our capacitor to charge up in the circuit. We have calculated that the time taken for the capacitor to charge up will be 2. The time taken for Vr to reach from 0V to 12V is equal to the time taken for the capacitor to charge from 0V to maximum voltage. The graph is illustrated using the cursors in the below image.
Similarly we can also calculate the voltage across the capacitor at any given time and the current through the capacitor at any given time using the below formulas. Where, V B is the battery voltage and I o is the output current of the circuit. The value of t is the time in seconds at which the voltage or current value of the capacitor has to be calculated. A series RL circuit will be driven by voltage source and a parallel RL circuit will be driven by a current source. RL circuit are commonly used in as passive filters, a first order RL circuit with only one inductor and one capacitor is shown below.
Similarly in a RL circuit we have to replace the Capacitor with an Inductor. The Light bulb is assumed to act as a pure resistive load and the resistance of the bulb is set to a known value of ohms. 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.
The inductor charges up quickly and hence a sudden voltage drop will be experienced by the resistive load R. Let us calculate the time taken for our inductor to charge up in the circuit. Here we have used an inductor of value 1mH and the resistor of value Ohms. Similarly, we can also calculate the voltage across the Inductor at any given time and the current through the Inductor at any given time using the below formulas.
The value of t is the time in seconds at which the voltage or current value of the Inductor has to be calculated. The circuit forms an Oscillator circuit which is very commonly used in Radio receivers and televisions. It is also very commonly used as damper circuits in analog applications. The resonance property of a first order RLC circuit is discussed below. The RLC circuit is also called as series resonance circuit, oscillating circuit or a tuned circuit. These circuit has the ability to provide a resonant frequency signal as shown in the below image.
Here we have a capacitor C1 of u and an Inductor L1 of 10mH connected tin series through a switch. Since the wire that is connecting the C and L will have some internal resistance, it is assumed that a small amount of resistance is present due to the wire.
