Hey good folks!
Consider this circuit..
http://upload.wikimedia.org/wikipedia/commons/9/9f/Voltage_stabiliser_OA.png
What I want to ask is what the Rv resistor does - is this the same as with calculating Rs for a regular Zener diode?
My textbook doesn't explain this, but it should be very simple since they are in parallell.
Is this correct interpretation?
Thank you for your help!
