What is a capacitor? How does a capacitor work? What does a capacitor do?

Let’s start by understanding a capacitor. A capacitor works by storing energy electrostatically in an electric field. What? Honestly I’m asking myself that too, so let’s try another way of thinking about it.  Let us start out with an analogy: you might know that capacitors are like batteries. In some ways this is a fair …

What is a resistor? How does a resistor work? What does a resistor do?

Before we can answer that we need to know: What is resistance? Let us start with conductors and insulators. Basically conductors allow electricity to flow and insulators stop electricity. Well that’s a rather simplified view, because there is more to it. For example air is normally an insulator, but with a large enough voltage it …
