An electric circuit is a combination of two or more electrical components that are connected together to accomplish a certain task.
Electrical and Electronics Engineering is the branch of engineering that deals with the study of generation, transmission, distribution, utilization, and operation of electric power, the electrical/electronic devices and components as well as the behaviour of electrical and electronic devices to different forms of electricity.
The transistor is a semiconductive device that is used for amplification and switching applications. The transistor is found in all the electronics. The most basic transistor is a BJT (Bipolar junction transistor) that is constructed from three doped semiconductor regions which are separated by two PN junctions. The three regions are known as emitter, base, … Read more
An amplifier is an active component that provides more ac output power applied to a load than input power applied to the circuit. The best example of an amplifier is a transistor or an op-amp.
An Active component is the one that can produce electrical power. Such components are capable of amplifying signals. Examples of active components include transistors and an op-amp.
Generally, power is defined as the ability of a body to do work. The electrical power is defined as the product of voltage and current. Power = Voltage * Current or P = VI SI unit of power is watt, and 1 watt is the power provided by a 1 Volt source creating a flow … Read more
An electrical transformer is a device that changes ac electrical power from one voltage level to ac electric power at another voltage level. The working principle of transformer is based on the action of a magnetic field. Basic Construction A transformer comprises two coils of wire forming windings that are wrapped around a ferromagnetic core. … Read more
The Power Backup Generator is a type of generator whose basic purpose is to provide power in case of interruption of main power. Such generators are found in commercial markets, homes, and industries applications. Another prominent use of backup generators is hospitals that typically require backup generators. When power loss occurs due to inclement weather, … Read more
