is the farad; but most practical capacitors will be rated in
microfarads (MF) or picofarads (PF). As with resistors, if the value
is not given, determine it by observing the color coding found on
many types of capacitors. Figure 1-7 is a table indicating the use
Six-Band Color Code for Capacitors.
Capacitors also come in many variations.
In addition to fixed
capacitors, you may often find variable, ganged variable, or
electrolytic (polarized) capacitors.
Figure 1-8 illustrates the
symbols used for some variations of capacitors.
