Current and Voltage Sources (With Definition) | Basic Electronics

The ultimate sources of power... voltage and current sources! These foundational pieces of electrical and electronics engineering are the way to describe *any* source of power in circuit design. They have their own dangers and differences in how they work in circuit analysis and in real life. In this tutorial, we'll go over definitions and learn what is needed to work with both voltage and current sources.

Calculate series and parallel resistor equivalence | Basic Electronics

Without getting into the math, we take a simple route to establish a more intuitive feeling of how resistors in parallel and resistors in series act. To increase overall resistance, you put resistors in series, to decrease overall resistance, you can put them in parallel. But there's more to it than that! Give it a watch to familiarize yourself better with these concepts. Then check out the site to get more information and a written tutorial including the math: https://www.circuitbread.com/tutorials/parallel-and-series-resistors

How to select resistor values for LEDs | Basic Electronics

We wanted to show how easy it is to select the right resistor for your next LED project. It's entirely possible that Josh broke it into more steps than he needed, but they're incredibly simple and easy to follow, so we won't get too upset with him. He goes over the importance of the forward voltage of the LED, the current needed but also the dangers of too much current, additional things to watch out for when selecting the resistor, all while explaining it both conceptually and showing the easy math required.

LEDs and Forward Voltage | Basic Electronics

Light emitting diodes, LEDs, are awesome and are nearly everywhere nowadays. We take a practical trip through the basics of LEDs, in particular their forward voltage and how *not* to apply a voltage across them. We compare the forward voltage of different LED colors. Finally, we destroy an LED in an incredibly unsatisfying way while seeing how current changes with voltage.
