1.	The chief advantage offered by the electronics is:(a) Differencing and stable amplification by Op-Amp(b) Stable amplification of power level by use of power transistor and SCR’s(c) Differencing and stable amplification of power level by Op-Amp(d) No amplification with the Op-AmpThe question was posed to me in a national level competition.I would like to ask this question from Controller Components in section Control System and Components of Control Systems
Answer» Correct option is (c) DIFFERENCING and stable amplification of power level by Op-Amp The explanation: Advantage of ELECTRONICS is that EVERY type of energy is converted into measurable and storage energy and electronically differencing to get the error signal and its AMPLIFIER.
