1.	The problem with the single operational difference amplifier is its(a) High input resistance(b) Low input resistance(c) Low output resistance(d) None of the mentionedThis question was addressed to me by my college professor while I was bunking the class.The origin of the question is Difference Amplifiers in portion Operational Amplifiers of Electronic Devices & Circuits
Answer» Correct OPTION is (b) LOW input resistance The explanation is: Due to low input resistance a large PART of the SIGNAL is lost to the source’s INTERNAL resistance.
