Thanks for the info, think I understand it now. That link is great. As for the time-delay circuit, believe it or not it was the charge on the base I wasn't understanding rather than the capacitor. I was sort of thinking of voltage as water pressure and envisioning it "pushing" against the...

Jony, thanks for the quick reply. It was reassuring: I could see this working as a time delay, but I thought there was also some way to make it oscillate that I just didn't get. Glad to hear that is not the case! Still, I don't understand why at t=0 there would not be a voltage difference...

Hoping someone can help me with some basic questions about resistor-capacitor oscillator (timer) circuits. I can put them together, I see them working, but I don't understand why! In the circuit in the attached drawing, if one installs the correct values of resistor and capacitor, I know...
