The movement of diaphragm in simple infrared analyser for gas analysis results in which of the following?(a) Variable resistance(b) Variable inductance(c) Variable capacitance(d) Variable conductanceThis question was addressed to me in homework.My doubt stems from Infrared Gas Analysers in chapter Industrial Gas Analysers of Analytical Instrumentation

Answer» RIGHT answer is (c) VARIABLE capacitance

To explain: The movement of DIAPHRAGM in simple infrared ANALYSER for gas analysis results in variable apacitance. The diaphragm forms one PLATE of the capacitor.
