Passive components
The passive components used in electronic circuits
all make use of one of the three fundamental
phenomena of resistance, capacitance and induct-
ance.
Just occasionally, two may be involved; for
example delay cable (described in Chapter 5)
depends for its operation on both capacitance and
inductance. Some components depend on the
interaction between an electrical property and,
say, a mechanical property; thus a piezoelectric
sounder (covered in Chapter 4) operates by virtue
of the small change in dimension of certain types of
ceramic dielectric when a voltage is applied. But
most passive components are simply resistors ...
