Electrical outlet Electrical outlets (also known as outlets, electrical sockets, plugs, and wall plugs) allow electrical equipment to connect to the electrical grid. The electrical grid provides alternating current to the outlet. There are two primary types of outlets: domestic and industrial. While not obvious from looking at them, the two sides of an electrical […]
An integrated circuit (IC) is an electronic circuit built on a semiconductor wafer, usually made of silicon. On this wafer, there are millions of miniaturized transistors, resistors, and capacitors, which are connected by metal traces. The ICs are powered by an external power supply for their operations. ICs perform specific functions such as data processing
The transistor is a non-linear semiconductor three-terminal device. The transistor is considered to be one of the most important devices in the field of electronics. The transistor has transformed many aspects of man’s life. There are two main functions of transistors, to amplify input signals and to acts as solid-state switches. The transistor acts as
The diode is two terminal semiconductor devices that allow an electric current to pass in one direction while blocking it in the reverse direction. The diode is made up of a semiconductor device with P-type material and N-type material. Typical material used in a diode is silicon and germanium. They conduct when a minimum forward
The inductors (also called as a coil or choke) is a passive two-terminal electrical component that stores magnetic energy when an electric current is passed through it. It’s an insulated wire wound into a coil around a core of some material (air, iron, powdered iron, or ferrite material) in a spiral form. The inductor is
The Capacitor is a passive electrical component, whose function is to store electrical energy and deliver it to the circuit when needed. The capacity of a capacitor to store electrical charge is known as the capacitance of that capacitor. It is denoted by (C). The unit of capacitance is Farad (F) and can range from,
The resistor is a passive electrical component whose function is to introduce resistance to the flow of electric current in an electrical circuit to limit the current. The magnitude of the opposition to the flow of current is called the resistance of the resistor. A larger resistance value indicates a greater opposition to current flow.
Some of the most commonly used electronic components are resistors, capacitors, inductors, diodes, LEDs, transistors, crystals and oscillators, electromechanical components like relays and switches, ICs, and connectors. These components have leads/terminals and are available in specific standardized packages, that the designer can choose to suit his application. SMT (surface mount technology) and through-hole are the
