RC circuits may seem simple—just a resistor and capacitor—but they’re the backbone of timing, filtering, and energy storage in electronics. Understanding how they charge and discharge unlocks ...

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

Well, it’s not “free energy,” however, yes, and can even use the same value resistor and capacitor in a ladder network shown in Figure 1, although differing values also can be utilized. Of course, ...
