Capacitors
You
need a number of components to build the circuits
in this chapter:
1 X 15 k resistor
1 X 22 μΡ electrolytic capacitor
1 X 220 μΡ electrolytic capacitor
1 X 470 μΡ electrolytic capacitor
1 X switch
As
usual, the resistor power rating and tolerance is of
no importance. The capacitor must, however, have a
voltage rating of 10 V or more. The switch can be of any
type, even an old light switch will do if you have one, A
slide switch is ideal, however, both common and cheap.
