Electronics Engineering

Electronics engineering is the electrical engineering discipline which deals with the fabrication, design, utilization, and operation of non-linear and active electronic components. The discipline can be further divided into an embedded system, analog electronics, digital electronics, and power electronics.

Electronic Engineering has changed the lifestyle of mankind since last few decades. After the invention of the solid-state device, the vacuum tubes are replaced by transistors and the size of equipment become compact.

Professional bodies for electrical and electronics standardization is Institue of Electrical and Electronics Engineering (IEEE) and Institution of Engineering and Technology (IET).

Zener Diode as a Regulator Explained with Example

A Zener Diode is a special purpose diode used for voltage regulation in reverse bias. Zener diode work under breakdown region for typical operation. A minimum current of Zener knee current must be maintained to keep the voltage regulated.

Full Wave Bridge Rectifier operation with Capacitor Filter

full bridge rectifier current flow during positive half cycle

The Bridge type full wave rectifier can convert an AC to DC by the mean of four diodes in such configuration that the output peak voltage remains equal to secondary of transformer peak. In each half cycle, a set of two diodes conduct and block the current alternately.

What is inductor, inductance and How it store energy

Inductor and inductance

An inductor is a passive circuit element which stores energy in the form of the magnetic field. Inductors are made of wrapped conducting wires or coil, to enhance the effectiveness of inductor number of turns are increased. An inductor is not anticipated to dissipate energy, it only stores energy and then delivers it to the circuit when required. Various symbols …
