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).

August 21, 2018August 20, 2018 by Shahab Yousafzai

In RL series circuit, during the inductor charging phase, the voltage across the inductor gradually decrease to zero and the current through the inductor goes to the maximum in five-times constant (5 taus).

What is inductor, inductance and How it store energy

November 7, 2018August 10, 2018 by Michal

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 …
