When should I use a transistor?
Electronic engineers use transistors to control the flow of electricity in circuits. They can operate up to billions of cycles per second, amplifying or switching electric currents. Specialized transistors can make colorful displays and sense light. It can amplify and switch electrical power and electronic signals.
What was the importance of the transistor?
The transistor went on to replace bulky vacuum tubes and mechanical relays. The invention revolutionized the world of electronics and became the basic building block upon which all modern computer technology rests.
What is the main function of capacitor?
A capacitor is an electronic component that stores and releases electricity in a circuit. It also passes alternating current without passing direct current. A capacitor is an indispensible part of electronic equipment and is thus almost invariably used in an electronic circuit.
What is transistor and uses?
Transistors are a three terminal semiconductor device used to regulate current, or to amplify an input signal into a greater output signal. Transistors are also used to switch electronic signals. The circulation of electrical current through all types of transistors is adjusted by electron addition.
What are the 2 types of transistors?
Two types of bipolar transistor are manufactured: npn and pnp. A field-effect transistor is a unipolar device constructed with no pn junction in the main current-carrying path. Also, two types of field-effect transistor are manufactured: N-channel and P-channel.
What is the symbol of diode?
Diode, an electrical component that allows the flow of current in only one direction. In circuit diagrams, a diode is represented by a triangle with a line across one vertex.
How do you represent a transistor?
The Transistor is a semiconductor device provided with three terminals called base, emitter and collector. It is used to work in electronic circuits as a rectifier, amplifier and switch. These symbols can be represented inside a circle.
What is unit of diode?
A diode is not a measurable quantity. Hence,it does not have a unit. Generally,for a diode,we measure characteristics like forward voltage drop,reverse voltage drop and reverse breakdown voltage which are usually measured in Volts.
