Here is another calculator that does
a good job.
Serial or parallel

resistance spreadsheet

As I have
learned so many times the hard way, there are several apps on the web that do
this automatically.
One I found to
be particularly helpful is this one that will calculate to any precision you
desire down to 1% with any values you might find in your junk drawer and it
tells you the deviation from your desired percentage and which of the values
will give the closest match.

Well gang, maybe the third time will bear fruit.? I shortened the
file name.? If this does not work then save the files PAR.* in a folder
and open with your spreadsheet program.? I did not test it in Access
but it works in Lotus.

I just tried to read the file PARALLEL.WK1 that came back form
Tekscopes and it was corrupted.? I will re-attach another copy.?
Lets see how this one works.

There was a thread a few weeks ago about a parallel resistance
calculator. I created a spreadsheet that allows you to instantly
select
a pair of 5% resistors to yield just about any resistance
value
desired. I used the @VLOOKUP function in Lotus 123 and every
value of
5% resistor from 10 Ohms up to 36MOhms is included. I will
attach a
copy to this note. Please reply if any improvements can be
incorporated.
