What does the transistor in the following circuit do. It is a 2N3565, and the circuit is used to measure changes in skin resistance. Is there a better method?
looks ok.
there are usually always better methods.
but that looks ok.
what does the transistor do?
changes conductivity between E and C
depending on current through the 'cans'
variable pot is to set fluctuations on
to the meter scale.
