Practical knowledge in electronics

Click For Summary
The discussion centers on the need for practical knowledge in electronics, particularly in designing real circuits beyond basic calculations of voltage and current. Participants suggest starting with foundational concepts such as Ohm's Law (V=IR) and understanding key electrical quantities like charge, current, and power. Recommended resources include "Practical Electronics for Inventors" and various educational websites like All About Circuits. Emphasis is placed on the importance of grasping theoretical principles to effectively utilize circuit schematics. Gaining a solid understanding of these fundamentals is essential for anyone looking to build and design circuits.

Hi guys , I don't know anything in electronics past how to calculate voltage and currents in circuits containing resistors and batteries . I lack the practical knowledge of how to construct real circuits . I want to know how to design real circuits . Can some one please point me to resources on how to design real circuits.Alot of websites are full of schematics but I do not know how to use those schematics to design circuits

Start with the most basic thing. V=I*R

Voltage = Current X Resistance

This one single equation can carry you a long, long way...and it always holds true without exception.

Consider perhaps getting some schooling?

I think zahero knows about Ohm's law - he said he can calculate voltage and current for simple circuits. But I agree, the theoretical foundations are important.
 
There was a similar question not long ago.

See
sparkfun dot com
discovercircuits dot com
tinaja dot com
allaboutcircuits dot com

and search out hobby sites.

and be sure to get your basic quantities well understood

charge
current
potential
energy
work
power

When you can explain each in simple terms you are ready to start building things.
 
Thread 'I thought it was only Amazon that sold unsafe junk'
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
