What is the technology of transistor?
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
What are the symbols used in electrical circuits?
Basic Electrical Symbols
- Ground or Earth. A ground symbol (IEC symbol 5017) identifies a ground terminal.
- Resistor. A resistor reduces current flow.
- Switch. Disconnects the current when open.
- Capacitor. A capacitor symbol shows two terminals running into plates.
- Fuse.
- Antenna.
- Inductor.
- Transformer.
What is the electronic symbol of PNP transistor?
PNP vs NPN Transistor
| PNP Transistor | NPN Transistor | |
|---|---|---|

| Collector-emitter voltage | Negative | Positive |
| Emitter arrow | Pointed in | Pointed out |
What is a symbol of NPN transistor?
NPN vs PNP Transistor
| NPN Transistor | PNP Transistor | |
|---|---|---|

| Collector-emitter voltage | Positive | Negative |
| Emitter arrow | Pointed out | Pointed in |
What is computer transistor?
In the digital world, a transistor is a binary switch and the fundamental building block of computer circuitry. Like a light switch on the wall, the transistor either prevents or allows current to flow through. A single modern CPU can have hundreds of millions or even billions of transistors.
What is the significance of the transistor to modern technology?
Transistors transformed the world of electronics and had a huge impact on computer design. Transistors made of semiconductors replaced tubes in the construction of computers. By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space.
How do you use a transistor in a circuit?
One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, the switch is off. When base voltage is present, the switch is on.
What does symbol represent in electronics?
An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit.
Why are symbols used in electronic diagrams?
Thus in circuit diagrams and schematics, graphical symbols identify and represent electrical and electronic devices and show how they are electrically connected together while drawing lines between them represents the wires or component leads.
What is a buzzer symbol?
The buzzer symbol is a semi-circle shape. To add a motor to the circuit, draw a circle with the letter M in the middle. A component called a resistor controls the flow of electricity through the circuit. All circuits generally contain a switch so that the flow of electricity can be turned off, and back on again.
What is the symbol for transistor?
PNP Transistor Symbol The PNP transistor symbol used in circuit diagrams is shown on the right in the diagram below. The PNP transistor symbol has an arrow pointing in. Compare it with the NPN transistor on the left. PNP transistors have emitter (e), base (c) and collector (c) terminals just like NPN transistors.
What are the terminals of a transistor?
Generally transistor is made of solid material which contains three terminals such as emitter (E), Base (B) and Collector (C) for connections with other components in the circuit. Some transistors contains fourth terminal also i.e. substrate (S).
What is the significance of arrow symbol in transistor?
The arrow in the symbol indicates the direction of flow of conventional current in the emitter with forward biasing applied to the emitter-base junction. The only difference between the NPN and PNP transistor is in the direction of the current. The transistor has three terminals namely, emitter, collector and base.
Why transistor is called a transistor?
transistor is a combination of the words transfer and resistance called transistor, it is so called because it is a resistor or a semiconductor device capable of amplifying the electrical signals when they are transferred from the input to the output terminals.
