Transistors are an essential part of many electronic devices and circuits! Benefits Of Transistor As A SwitchĪ transistor can be used as a switch because it can control the flow of electricity. For example, if a circuit is getting too much power, the transistor can be used to turn OFF the flow of electricity and prevent damage to the components. When the transistor is turned ON, the motor will be able to run freely.įinally, transistors can also be used to regulate power in an electronic circuit. When the transistor is turned OFF, the motor will not be able to operate. Similarly, transistors can be used to control motors. When the light is ON, the current can flow freely through the circuit and illuminate the bulb. When the light is OFF, the transistor prevents current from flowing through the light bulb. For example, you could use a transistor to turn a light ON or OFF. In most cases, transistors are used to turn something ON or OFF. Transistors can be used to control the flow of electricity in a circuit, which makes them ideal for use as switches. Regulating power in an electronic circuit Some of the most common applications are: Transistors can be used as a switch in various electronic applications. They are also used in computers to amplify the signals from the keyboard and mouse. The amplifiers increase the strength of the signal. The transistor as an amplifier is used in audio systems, radios, and televisions. The main advantage of using a transistor as a switch is that it can control a large amount of current with a small amount of current. The digital circuits are the ones that use transistors to store the data in the form of bits (0 or The transistor as a switch is used in digital circuits. The transistor as an amplifier is used to amplify the voltage or current. The transistor as a switch is used to turn ON or OFF a circuit. What Are Transistors as a Switch?Ī transistor is a three-terminal semiconductor device that can be used as a switch or amplifier. This information is intended for beginners who want to learn more about transistor technology. We will also provide a few examples of applications where transistors are commonly used as switches. ** The circuit is exactly similar to what is given above.In this article, we will discuss the basics of how a transistor can be used as a switch. Note: Before building the circuit on a breadboard, it is first simulated on “ Every circuit” app. ** Hence we get 0(LED is off) at the output when input is 1 and 1(LED is ON) at the output when input is 0. Hence LED turns off i.e, 0 at the output. All current flow from collector to Ground i.e, through the path of minimum resistance. And due to this no current flow from resistor to LED and then to ground. So it acts like a closed switch from collector to emitter i.e, almost zero resistance between collector and emitter. In this case, there is some threshold voltage at the base of the transistor. ![]() All current flow from the resistor to LED and then to ground i.e, through the path of minimum resistance. And due to this no current flow from collector to Ground. So it acts like an open switch from collector to emitter i.e, infinite resistance between collector and emitter. ![]() In this case, there is no voltage at the base of the transistor. And whenever there is no or less voltage then threshold voltage at the base, it acts like an open circuit from collector to emitter. Whenever there is some threshold voltage at base, transistor acts like a closed switch from collector to emitter. Ground- Negative terminal of the battery.īC547 Transistor acts like a switch in this circuit. Output indicator i.e LED is connected between collector and emitter(Gnd).ĥ. Emitter goes to Ground i.e, -ve terminal of the battery.Ĥ. Logic inputs is given to base of the transistor through 100 ohm resistor.ģ. ![]() Collector goes to +ve terminal of battery through 1k resistorĢ. This is the circuit we are going to build on Breadboard.ġ. You can also watch the video below for quick reference: So when the input is 0, the output is 1 and when the input is 1, the output is 0. There is only one input and one output in a NOT Gate. NOT gate is a Logic Gate and called so because NOT means “Opposite”. **Read Similar Article: And Gate using Diodes But do you know, you can build your own NOT Gate on Breadboard? So in this post, you will learn how to make a NOT Gate using a transistor on a Breadboard. I am sure you must be familiar with a NOT Gate, it’s Truth Table, Logic symbol, and its working.
