About Us 

Welcome to Electronic FAQ – your go‑to space for simplifying the world of electronics!

We created this blog with a single mission: to make electronics easier to understand for everyone – from beginners taking their first steps with circuits to enthusiasts seeking practical solutions, tips, and explanations.

Here, you’ll find:

  • Step‑by‑step guides that break down complex concepts into plain language.

  • FAQs and troubleshooting help for common electronic components, devices, and projects.

  • Learning resources that bridge theory and hands‑on practice.

  • Project ideas and DIY experiments to spark curiosity and encourage innovation.

At Electronic FAQ, we believe electronics should be accessible, engaging, and fun. Our aim is to build a knowledge hub where learners, hobbyists, and professionals alike can find reliable answers and inspiration.

Thank you for visiting our blog – we hope it becomes a trusted part of your learning journey.

Stay curious. Keep building. Never stop exploring!

Would you like me to make two versions—one formal and professional (for credibility with students and professionals) and another casual and friendly (to connect with hobbyists and beginners)?

What happens to the energy stored in an inductor carrying a current?

By
Can the Energy Stored in an Inductor Be Used Practically? Applications, Benefits, and Real-World Examples. Why does an inductive load create sparking across contacts?  An inductor stores energy in the form of a magnetic field as long as current is flowing through it. As the current stops, the magnetic field began to collapse. Collapsing magnetic flux is also a rate of change of magnetic flux that will induce a large voltage spike (back EMF) across it. Energy stored in an Inductor:  Since this induced voltage is parallel to the inductor coil, it decays by converting it to heat across the coil resistance. During this process, the coil generates a magnetic field again due to the flow of decaying current through the coil, which results in electromagnetic interference during radio operation and sparking across open contacts. Adverse effects of stored energy in an inductor:  Can we put this back-EMF into use? Yes. Practical Use of Stored Energy in an Inductor:  Spark-ignit...

What is biasing in electronics?

By
What is DC Bias Voltage used in Electronic circuits? — Definition, Importance & Practical Examples DC bias is simply a deliberate addition of a DC voltage to a (circuit) node to offset its operating voltage level. Voltage divider bias in a common emitter amplifier:  The most common and popular example of DC bias is the voltage divider bias in a common-emitter amplifier. What will happen if the DC bias is not given to the base of the above circuit? The transistor will act like a rectifier; it will amplify only the positive part of the signal, creating a distorted output that we don't want. Purpose: The purpose of the DC bias in the above circuit is to keep the base DC offset voltage sufficiently high to keep the base-to-emitter junction forward-biased all the time, considering the subtractive effect of the negative-going excursion of the AC input signal and power supply voltage variations. The typical value is 1.2V for the 12V VCC. Biasing is not always DC; it can be AC: AC bias...
