Optocoupler Optocoupler: Its Types and Various Application in DC/AC Circuits

Opto-coupler is an electronic component that transfers electrical signals between two isolated circuits. Optocoupler also called Opto-isolator, photo coupler or optical isolator.

Often in circuits, especially low voltage or highly noise sensitive circuits, Optocoupler is used to isolate circuitry to prevent electrical collision chances or to exclude…

Kirchhoff's Law Kirchhoff’s Circuit Law

Today we will learn about Kirchhoff’s Circuit Law. Before going into detail and its theory part, let’s see what actually it is.

In 1845, German physicist Gustav Kirchhoff was described relationship of two quantities in Current and potential difference (Voltage) inside a circuit. This relationship or rule is called as Kirchhoff’s circuit Law.

DC Circuit Theory DC Circuit TheoryWhat is DC?

In elementary school, we learned that everything is made by atoms. This is a product of three particles: Electrons, Protons and Neutrons. As the name suggest Neutron does not have any charge whereas Protons are positive and Electrons are negative.

In atom, electrons protons and neutrons stay together in a stable formation, but if by any…

Wein Bridge Oscillator Wein Bridge Oscillator

In this tutorial, we will learn about Wein Bridge Oscillator which was developed by a German physicist Max Wien. It is originally developed for calculating the capacitance where the resistance and the frequency are known. Before going to the further in depth discussion about what actually the Wein Bridge Oscillator and how it is used, let’s see what is Oscillator and what…

RC Phase Shift Oscillator RC Phase Shift OscillatorWhat is Oscillator?

An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. We all have devices which need oscillators, traditional clock that we all have in our home as a wall clock or wristwatch, various type of metal detectors, computers where microcontroller and microprocessors are involved all…

Active High Pass Filter Active High Pass Filter

Previously we described about Passive High Pass Filter and Active Low Pass Filter, now it is time for Active High pass filter. Let’s explore what is an Active High Pass Filter.

 

What is it, Circuit, formulas, curve?

Same as like passive low pass filter, passive high pass filter works with passive components, Resistor…

Active Low Pass Filter Active Low Pass Filter

Previously we described passive low pass filter, in this tutorial we will explore what is an Active Low Pass Filter.

What is it, Circuit, formulas, curve?

As we know from previous tutorial, Passive low pass filter works with passive components. Only two passive components resistor and capacitor is the key or heart of a passive low pass filter…

TRANSFORMERS Basics of Transformer

Transformers generally, are devices capable of converting quantities from one value to the other. For this Article, we will be focusing on the Voltage transformer which is a static electrical component capable of converting AC voltage from one value to the other without changing the frequency using the principles of electromagnetic induction.

Passive High Pass Filter Passive High Pass Filter

Previously, we discussed the Passive Low Pass Filter; now it is time to look into the passive high pass filter. A passive high pass filter is an electronic circuit that allows high-frequency signals to pass while blocking low frequencies below a predetermined cutoff point. 

Same as before, if you look into the name, it shows “Passive”, “High…

AC Circuit Theory (Part 2): Peak, Average and RMS Values AC Circuit Theory (Part 3): Peak, Average and RMS Values

These AC circuits series has taken us on a journey which has seen us discuss what AC really is all about, how its generated, some histories, concepts behind AC, its waveform, characteristics and some properties. Today we will be going over some terms and quantities associated with the Alternating Current.

 

Peak Value of An AC Waveform…
Passive Low Pass Filter Passive Low Pass Filter

This tutorial is about Passive Low Pass Filter, a widely used term in Electronics. You will hear or use this ‘technical’ term almost every time in your studies or in your professional career. Let’s explore what is special about this technical term.

  What is it, Circuit, formulas, curve?

Let’s start from the name. Do you know what is passive?…

Thyristor What is Thyristor and How it works?

In general, Thyristors are also switching devices similar to transistors. As we already discussed, Transistors are the tiny electronic components that changed the world. Today we can find them in every electronic device like TVs, mobiles, laptops, calculators, earphones, etc. They are adaptable and versatile, but that doesn’t mean that they can be used in every…
