Basic Op-Amp Circuits

Q1: A basic series regulator has

A an error detector

B a load

C a reference voltage

D both an error detector and a reference voltage

ANS:D - both an error detector and a reference voltage

A basic series regulator is composed of a Zener diode for voltage reference and a BJT which serves as the error detector. It detects whether it need to give less or more current to the load via the reference of zener diode and a feedback loop.
