Electronics and Communication Engineering Linear Electronic Circuits
What is Electronics? It is the branch of science and Technology which deals with the motion of electrons in various systems or devices. Electronics includes devices like diodes,transistors,rectifiers,etc.by these devices many systems work efficiently. The world is amazing by these very very tiny components which are embeded in to the systems(like radios,computers,etc.) for their working.
What is a circuit? It is any closed system consists of various components(Electronic) linked to each other to make a circuit functional. This circuits is of very small in size. Even in chips we have plenty of circuits present in them.
Electronic components(or)devices 1)Diodes 2)Rectifiers 3)Transformers 4)Transistors 5)and etc.
Diodes Diode is a semiconductor which is made of with the combination of the p and n type semiconductors. It can be denoted by the symbol The main characteristic of the diode is it can block the current in one direction and allows the flow in another direction. Diodes are mostly made up of Silicon and Germanium.
Rectifiers Rectifier is one which converts AC current into DC current known as rectification Number of diodes are used in rectifiers. If only one diode is used in a rectifier it is called as a rectifier the only difference is a rectifier converts AC current to DC current. There are two types of rectifiers one is half wave rectifier and another is full wave rectifier. Rectifiers are used in power supplies and in radio signals.
Transformers These transformers also did the same thing as rectifiers as taking ac voltage or current throught it and convert it to dc supply. There are two types of transformers namely step up,step down tranformers. Mutual induction process is takes place while converting from ac to dc. And the number of primary and secondary coils are responsible for the step up and step down transformers.
Transistorss if we add an another semiconductor to the diode it becomes a transistor.That is p-n-p or n-p-n transistors are now the well known transistors in their function. The structures of these trasistors are here B is base,C is collector and E is emitter. Transistors are used to amplify the electrical signals.
contd.. The transistor is the fundamental building block of modern electronic devices an advanced microprocessor, as of 2009, can use as many as 2.3 billion transistors. The transistor's low cost, flexibility, and reliability have made it a ubiquitous device There are two types of transistors as BJT,FET.
