Resistors will be called out by their resistance value
in 0 (ohms), kO (kilohms), or MO (megohms). Certain
types of resistors
will have the value printed on the
body, while others will be identified by a color code .
The colors of
the bands and the value will be given in
the steps, therefore the following color code is given

Capacitors will be called out by their capacitance
value in JLF (microfarads) or pF (picofarads) and type:
ceramic, Mylar*, electrolytic, etc.
Some capacitors
may have their value printed in the following man-

First digit of
capacitor's value: 1
NOTE: The letter "R" may be used at times to signify a
decimal point: as in: 2R2 = 2.2 (pF or JLF).
Second digit of
capacitor's value: 5

Multiplier: Multiply the
first
& second digits by
the proper value from the
Multiplier Chart.
To find the tolerance of
the capacitor, look up
