In the basement of my house there's an obsolete device hanging from one of the walls:A Cable TV dispatcher / splitter, amplifier. With a few separate signal paths for bidirectional data (internet).I've been looking at it for 6 years...
The element14 Experimenting with Magnetic Components Challenge is a design competition for electrical engineers where they are provided a collection of inductors, chokes, line filters and transformers to conduct experiments and blog about what they learned. The winners receive great prizes.
I wanted to give you an update on the winners announcement.
The judges and I have been reading all of the participants blogs, ranking them, and making the final decision of the winners.
There was excellent work by all so it was tough to decide o...
Inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil.

Summary
After 5 weeks doing experiments and learning about analog electronics and magnetic components it is time to try to design and build something practical, my DIY Inductive Sensor.
Thanks to element14 and Bourns during these weeks I have ...
In this blog, I will calculate the non-ideal parameters of the inductor and do some simulation based experiments for the inductor.For calculating the inductance and Rdc, I will use my Tenna Handheld LCR meter. I have chosen the 1mH inductor. As ...
When we work with RLC Circuits we need to know about Resonance and Low Pass and High Pass Filters Let’s start Experimenting with Resonance. What is Resonance in Electronics?Resonance is a phenomenon that occurs in electric circuits consisti...
