This video explains the role of resistors in electronic circuits and how Ohm’s Law defines the relationship between voltage, ...

Try an experiment. Next time you are in a room with someone, ask them to name everything in the room. Only certain kinds of people will say “air” or “light.” For most ...

I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

Be careful with single-phase motors, as most single-phase motors have components to help them start or continue to run ...

We often run into the situation where there are two capacitors, one of them charged up to some voltage level and the other at some lower voltage level which, for purposes of this discussion, we will ...

The modern world runs on electricity, and wires are what carry that electricity to every light, television, heating system, cellphone, and computer on the planet. Unfortunately, on average, about 5 ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...
