[sdiy] really basic question

[John L Marshall]

Are you saying that if two resistors that are at the high end of the
tolerance are connected in series that the result will be out of tolerance?

Add two 100k resistors 101k + 101k = 202k still 1%

I prefer to think in terms of conductance in parallel circuits.

The reason I think in terms of conductance in parallel circuits is it is
eaiser to visualize what is going on with parallel circuits that include
capacitors and inductors.

Gt = G1 + G2 + .... Gn

Result is 50.5k still 1%

What am I missing?

Take care,
John
