When load current flows into the feedback circuit, the configuration is said to be
(a) Current-shunt feedback
(b) Voltage-shunt feedback
(c) Voltage-series feedback
(d) All of the mentioned
I have been asked this question by my college director while I was bunking the class.
This intriguing question originated from Block Diagram Representation of Feedback Configurations topic in section Operational Amplifier Characteristics of Linear Integrated Circuits
