Electronic Basics

While LEDs may be everywhere now, that obviously wasn't always the case. So how did we go from no LEDs to LEDs in nearly everything on the planet? As we researched it, we were ...

We took apart two LED lightbulbs, a CREE LED bulb from 2014 and a Philips bulb from 2018, and compared their build quality, the electronics, and their overall design. It was ...

Ask an Electrical Engineer is a series where frequently asked questions from non-engineers will be answered by an engineer. For this video, our main topic is all about LEDs (Light ...

Dimming is the process of varying the light output of a light source. This is done to set the ambience or to save energy when full light output is not really needed. Most of the ...

We've discussed a lot about LEDs like how it works in a semiconductor level, its pros and cons, and how an individual LED can be dimmed through constant current reduction (CCR) or ...

Why do we need a resistor for an LED? Once you pass the forward voltage, a slight increase in voltage makes a huge increase in current. You don’t wanna blow things up!

LEDs are better than other light sources in most applications. While they are more efficient, there are a lot more things to consider when buying a lightbulb than just how much ...

Before we can get too deep into voltage dividers, it is essential to have a good understanding of what happens with Parallel and Series Resistors. Once you understand how a ...

Resistors are the most common electronics component in the world. They’re used in many forms of circuits as voltage dividers, to keep current levels under control with things like ...

In normal conversation, power is often interchanged with a lot of similar but actually different words - energy is a big one. Power is the amount of energy that is expended over a ...

I have to admit, I’m biased. I think LEDs are awesome. But, really, the reason I’m biased and love them so much is because they’re just so cool. I’ve found that as I replaced the ...

Every circuit has a power source, or else it won’t do much. While the actual power source can vary wildly, they all fit under the two general titles of “voltage source” or ...

Potentiometers. Pots. Trimmers. Rheostats. If you’ve done very much with electronics, you’ve heard at least a couple of these words. Maybe you’ve heard them interchangeably and ...
