1.	If the differential amplifier gives zero as output then it infers which of the following (Reference output is given to the positive terminal and sample output is given to the negative terminal)?(a) The concentration of silica in sample and reference solution is equal(b) The concentration of silica in a reference solution is more than that in the sample solution(c) The concentration of silica in sample solution is more than that in the reference solution(d) Further processing is required to come to any conclusionThe question was asked in homework.Asked question is from Silica Analyser topic in portion Dissolved Component Analysers of Analytical Instrumentation
Answer» Right option is (a) The concentration of silica in SAMPLE and reference solution is EQUAL The explanation is: If the differential amplifier gives ZERO as output then, it means that the concentration of silica in sample and reference solution is equal. It means that the photodetectors’ output is equal.
