How does a circuit work?
A circuit does what we want because we use different devices in a special
combination to control the flow of electrons. These devices were previously
invented by engineers and scientists\who had some application in mind.
These devices are called resistors, capacitors, inductors, transistors,
transformers, etc. There are also now logic devices that can be used in
digital circuitry. These may look at a high or low input signal or combina-
tion of signals and give a logic response accordingly. Basically all
circuits are designed to take one or a number of inputs and convert them to
a different but desired output. For example, I might want to take an
alternating current and convert it to a direct current. I would do this
using a rectifier circuit. This circuit would contain a special combination
of devices that work together to yield a nearly direct current as an output.
This current could then be used for something else like charging your
