wt said:When using a potentiometer as a voltage divider, any potentiometer will do
since it is just the ratio i.e. whether 10k or 100k or 1Meg.
What I want to know is are there any factor we should decide on when
choosing either 10k,100k or whatever.
There are at least two concerns.
1. How much power are you willing to dump into the
2. How much current must the divider supply to the load on
the voltage tap? (Or alternately, what maximum output
impedance can you tolerate?)
