Hello,
Please consider a voltage divider bias circuit in the attachment below. There is something weird going on here. This configuration as it is, gives a Vc output of approximately 1.2 VDC. Why is it that when Vs power supply is "off" and when "S1" closes, Vc raises to 3.35 VDC ???
Even if I turn Vs "on" but keep it's voltage output to 0 volts, Vc still raises to 3.35VDC???
The only way I can get rid of this unexplained issue is if I keep "S1" open.
All help appreciated!
