The dynamic response is limited. This is an entirely easy means to specifically get guide by on-line. The photoconductive cell is a two terminal semiconductor device whose resistance varies inversely with the intensity of light that falls upon its photosensitive material shows a typical photoconductive cell and the schematic symbol. 2. One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect (the generation of electricity when stress is applied) also exhibit the converse piezoelectric effect (the generation of stress when an electric field is applied). How can you define electromyogram (EMG)? Harikesh Yadav June 13, 2017 ECE MCQ PDF, General. The […], What do you understand by bioelectric potentials? This set of IOT Multiple Choice Questions & Answers (MCQs) focuses on “Arduino”. Since the other end of the tube is open to atmosphere, the pressure obtained using the piezometer tube is gauge pressure. Mechanical Engineering MCQ Question Papers: DRDO, ISRO, Interview. The LVDT can be used in all applications where displacement ranging from fractions of a few mm to a few cms have to be measured. A lead thermometer may be used to measure temperature as low as -250°C and below these temperature constant and manganin thermometers are used. Load cells typically contain multiple strain gauges aligned and wired in a Wheatstone bridge circuit. Inductive & Displacement Transducers - MCQs with answers 1. Q7. Answer: a Explanation: There are basically two types of transducers. Linear inductance b. Also, to reduce the surface tension and capillarity effects.
