Capacitors

We're

going to take a close look at a new type of compo-

nent ttiis chapter: the

capacitor.

We shall see how

capacitors function, firstly in practical experiments

which you can do for yourself and then, secondly with a

bit

of theory

{boring, boring, boring!

— Who said that?)

which will show you a few things that can't easily be

demonstrated in experiments.

So,

let's get started. What exactly makes up a capacitor?

Well,

there's an easy answer: a capacitor is made up from

two electrically conductive plates, separated from each

other by a sandwiched layer of insulating material.

Fig-

ure 4.1 gives you a rough idea.
