1.	For proper feedback in a process control element, it is required to ________(a) measure P(b) measure set point(c) measure error(d) measure comparatorI had been asked this question in an interview for internship.This is a very interesting question from Process Control System topic in chapter Transducers of Electrical Measurements
Answer» The correct option is (a) measure P To explain: In a process control ELEMENT, proper feedback is obtained by measuring the PARAMETER P. ELECTRICAL INPUT is REQUIRED in most of the process controllers as they are electronic in nature.
