In this video, I will try to explain you the structure and working principle of thyristors used in fast switching duty in power electronics circuits. Thyristors are made up of four semiconductors of type P and type N. Thyristors are abbreviated as SCR, which is the initials of the words Silicon Controlled Rectifier.

In this video, I will explain the working principle of the liquid level indicator circuit, which is an example of a hobby electronic circuit that you can easily install on the breadboard, using only BJT transistor, LED and resistor. This example will be very useful in terms of understanding the working principle of the BJT Transistor for the new learners. This circuit is widely used as hobby electronic circuits. Towards the end of the lesson, I will show the simulation of this circuit on Proteus. By the end of this lesson, you will have a better understanding of both transistor's working principle and the use of Proteus.

Hello friends! In our previous lessons we tried to explain how fixed and variable resistors are used in the circuit. Through the examples, we analyzed the basic usage principle of these resistors and what their roles are in the circuit. And in this lesson, we will analyze the dependent resistors, which is the last lesson of our range of resistors. Dependent resistors are of three types. These are resistors depending on light, heat and voltage. Now, let’s have a look their structure and how they are used in the circuit.

Hello friends! In our previous lesson, we studied the basic duty of fixed resistors in the circuit. We have seen how these resistors are used in the circuit through Ohm's Law. We mentioned that we will study the resistors in three groups. In this lesson, we will study the variable resistors. Variable resistors are of three types. These are Potentiometers, Trimpot and Rheostat. Let's analyze their structure and how they are used in the circuit. 00:00 Introductor 00:29 Potantiometer 03:31 Trimpot 04:23 Rheostat Join this channel to support us: https://www.youtube.com/channel/UCFbUjfYYYr6Adt1I0jnECTw/join

Hello friends! In this lesson, I will try to explain you the types of resistors used in almost all electrical and electronic circuits. As in other circuit devices, there are many types of resistors. We will study what these are and how they are used. The unit of the resistors are ohms and they are indicated with the letter R in the circuit. As you can see here, we can analyze the resistors in three groups: Fixed Resistors, Variable Resistors and Dependent Resistors. Variable and Dependent resistors are also available in different versions. I will try to explain the types of resistors in three different videos so that the lesson gets not too long. In this lesson we will analyze Fixed resistors. Now let's take a look at the shapes, symbols, features and how they are used in the circuit. All of the resistors you see in the figure are fixed resistors. The values of these resistors do not change with environmental effects and are used to fix the circuit current at a certain value. The reason of the different structures is that the current intensity of the circuit to be used is different. The materials used in fixed resistors differ. The value of these resistors can either be written on or understood by looking at the color codes on them. There are two types of circuit symbols used for fixed resistors. It is possible to come across the use of both of these symbols. To better understand the basic role of resistors in the circuit, we can analyze this figure. A current occurs as a result of the movement of electrons in an electrical circuit. The force that creates current by moving these electrons is voltage. It is the resistance that limits the current by reducing the flow of electrons. There is a Current = Voltage/Resistance relationship between the three of them. If we show them in letters, I = V / R. This ratio between the three is Ohm's Law. We can show this shape as an electrical circuit. For example; take the resistance value 2.2kΩ and the voltage value 9V on this circuit. According to Ohm's Law, the current is approximately 4mA. If the resistor value increases here, the current value decreases. Because, resistance and current intensity are inversely proportional. So how to use a fixed resistor circuit, now let's look at it. Let's learn the basic usage through a simple circuit. For example, let's have a 9V voltage source. With this source, we will ensure that a LED is properly illuminated. When we connect the source directly to the LED, a current flows through the circuit and the LED gives light. However, since this current flowing through the circuit is high, the LED burns out after a short time and no current flows through the circuit. Because, for a LED to work properly, the current that it flows on it must be between 15 and 30 mA. But if we connect the LED to this source together with a resistance of 330Ω, the LED will light for a long time without any damage. Because the current flowing through the circuit will be around 27mA. The current flowing through the circuit should be adjusted with suitable resistors in order to prevent damage to the circuit elements used. If we want to use this LED properly with 12V voltage source, this time we should use higher one such as 470Ω resistor. Thus, since a current of approximately 25mA will flow through the circuit, LED gives light for a long time without any damage. It doesn't matter if the resistance is here or there. Because, as the same current will flow through all circuit elements in series circuits, this will not change the current intensity flowing through the LED. Let's look at another example of how to use fixed resistors. Let's connect 100Ω resistor to a power source as shown here. According to the current flowing through this circuit, our lamp gives a certain amount of light. When we connect the same power source to this lamp with a resistor of 330 Ω, we can see that the brightness of the lamp is slightly reduced as less current will flow through the circuit. When we connect a higher resistor such as 470Ω, the current will reduce even more, so the brightness of the lamp will be reduced a little more. As seen, the resistance value has determined the intensity of the current flowing through the circuit. If we increase the resistance value even more, the current flowing through the circuit will be much lower and maybe not enough for the lamp to light up. When we need higher resistors, we can connect the resistors in series. Because in series connected resistors, equivalent resistance is equal to total value of resistors.

Hello friends! In this lesson, I will explain you the main differences between BJT and JFET transistors used in switching and amplifying in electronic circuits.

Hello friends! In this video, I will explain the concepts of current and voltage. Anyone who learns electrical and electronics constantly uses these concepts but has difficulty in understanding. An electrical circuit basically contains a power source and a load. The load is a lamp here. We have a cable carrying the current that will make this lamp turn on. We define the current as the amount of load per unit time. So what does this mean, let's see together.

Hello friends! In this video, I will explain you in detail the structure and working principle of the diode, the most basic circuit element of electronics. Well, where is the diode used? Now let's take a look. One of the places where diode is used is the bridge type full wave rectifier circuit. In other words, it is the circuit used in the power source or adapters. In this circuit, 4 diodes are used. Thanks to this circuit, the negative alternatives of Alternating Current are converted to positive. This is the first step in converting AC to DC. An example of where diodes are used is BJT transistors. It consists of combining N and P type materials as well as diodes. While the diode is formed in the form of PN, the BJT transistor consists of a combination of PNP or NPN. Thyristor and Triac are also formed in similar way. They consist of four N and P type materials combined in the form of NPNP. Hereby, I have tried to explain the basic structure and certain usage areas of the diode.
