You don't, you read the tolerance markings. If you measure the resistor and it is outside the marked tolerance it is bad.

### How do you calculate percentage error for equipment?

Look on the equipment for where it says the plus or minus figure
for accuracy (for a burette it is usually + and _ 0.1cm3) divide
this by the amount you measured , times 100 to make it a
percentage. ---- ---- Percentage Error = Maximum Error /
Measured Value X 100 For example.
Maximum Error for the following apparatus are:
Balance = +/- 0.01
Pippette = +/- 0.1 And the Measured value for each
are:
Balance = 0.15
Pippette = 25 Then...the percentage error is:
Balance percentage error = 0.01 / 0.15 X 100 = 66.66%
Pippette percentage error = 0.1 / 25 X 100 = 0.3% You can
now also work out your maximum total error.
Maximum total Percentage error = Balance Percentage error +
Pippette Percentage error
Maximum total percentage error = 66.66 + 0.4 = 67.06%
