What is Electronics?
Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit the electron.See More: Types of Computers
There are various basic electrical and electronic components which are commonly found in different circuits of peripherals. In many circuits, these components are used to build the circuit, which is classified into two categories such as active components and passive components.
Active components are nothing but the components that supply and control energy. Passive components can be defined as the components that respond to the flow of electrical energy and can dissipate or store energy. These components can be found in numerous peripherals like hard disks, motherboards, etc.See More: Opera launches faster version with support multi language target indian maket
Many circuits are designed with various components like resistors, capacitors, inductors, transistors, transformers, switches, fuses, etc. Therefore, this article gives a brief information about different types of electronic and electrical components that are used in various electronic and electrical projects. The following paragraphs describe each & every component in detail with diagrams.
Major Electrical and Electronic Components
The major electrical and electronic components used in electrical and electronic projects mainly involves these components like resistors, capacitors, fuses, transistors, integrated circuits, relays, switches, motors, circuit breakers etc. In many circuits, these components are used to build the circuit, which is classified into two categories such as active components and passive components.
Active and Passive Components
Active components rely on a source of energy (usually from the DC circuit, which we have chosen to ignore) and usually can inject power into a circuit, though this is not part of the definition. Active components include amplifying components such as transistors, triode vacuum tubes (valves), and tunnel diodes etc.
Passive components can’t introduce net energy into the circuit. They also can’t rely on a source of power, except for what is available from the (AC) circuit they are connected to. As a consequence, they can’t amplify (increase the power of a signal), although they may increase a voltage or current (such as is done by a transformer or resonant circuit). Passive components include two-terminal components such as resistors, capacitors, inductors, and transformers etc.
