Reading 5band
resistors:
5band resistors are easy to read if you remember two simple points. The first
three bands provide the digits in the answer and the 4th band supplies the
number of zero's.
Reading
"STANDARD VALUES" (on
5band resistors)
5band resistors are also made in "Standard Values" but will
have different colours  and will be confusing if you are just starting out.
For instance, a 47k 5% resistor with 4bands will be: yellowpurpleorangegold.
For a 47k 1% resistor the colours will be yellowpurpleblackredbrown. The
brown colourband represents 1%.
The first two colourbands for a STANDARD VALUE in 1% or 5% will be the SAME.
These two bands provide the digits in the answer.
It's the 3rd band for a 5% resistor that is expanded into two bands in a 1%
resistor. But it's easy to follow.
For a standard value, the 3rd band in a 1% resistor is BLACK. This represents a
ZERO in the answer. (For 5band resistors BLACK represents a ZERO when in the
third band. This is
different to 4band resistors where black represents the word OHMS! If the third
band is BROWN, the answer will be 1).
So the 4th band has to represent oneless
ZERO and is one colour UP THE COLOUR CHART!
In other words the 3rd and 4th bands (combined) on a 1% resistor produces
the same number of zero's as the 3rd band on a 5% resistor!
Resistors come in a range of values and the two most common are the E12
and E24 series. The E12 series comes in twelve values for each decade.
The E24 series comes in twenty four values per decade.
E12 series  10, 12, 15, 18, 22, 27, 33,
39, 47, 56, 68, 82
E24 series  10, 11, 12, 13, 15, 16, 18,
20, 22, 24, 27, 30, 33, 36, 39, 43, 47, 51, 56, 62, 68, 75, 82, 91
