Resistors will be called out by their resistance value
in 0 (ohms), kQ (kilohms), or MQ (megohms). Certain :
types of resistors will have the value printed on the bbil
body, while others will be identified by a color code. 1/2-WATT
The colors of the bands and the value will be given in —__{i aA
the steps, therefore the following color code is given on
for information only.
