There are two basic ways to connect electronic components with two terminals: series and parallel. In this episode, we examine those two types of circuits and show how to calculate equivalent resistance.

Power is the rate of doing work, and for electricity, that means the rate in which energy is converted in a circuit.

Let's look at the resistor and how it affects current and voltage in a circuit. Here's a hint: if you know two of either voltage, current or resistance, you can solve for the third.

In this episode, we'll explore how electric current flows through a circuit.

I can do anything, I tell you! It’s always an excuse to get that next tool, or buy it again because I don’t remember buying it two years ago…
Thanks for this! I was left with one more question though. Maybe this is obvious: more power should mean more vapor. But, if it’s heat that…
What a great article. I have been toying with the idea of creating a smoke machine for an electric rc plane using vape mods. I am not…
Well, I did wind up building it. Lot of fun so far. It’s only in the basic breadboard stages so I’ll post pictures later. I don’t have much…
If you measure the resistance of your test leads, I think you’ll find them equal or greater than the vape coil. If that’s the case, 2/3 or…
There are many studies that confirm this. Here is a brief synopsis…
