a) The saturation voltage V CF of silicon transistor is more than germanium transistor. These short solved questions or quizzes are provided by Gkseries. 317. Q17. They are designed to measure bioelectric potentials near or within the cell. These strain gauges are typically used as elements in a Wheatstone bridge circuit, which is used to make the measurement. A load cell is a transducer. advertisement. Measurement of temperature using the thermometer. A, Q3. Respiratory system C. Electrocardiogram system D. Nervous system Q2. Answer.2. Variable resistance: transducer is a strain gauge. Strain gauges typically require an excitation voltage and provide output sensitivity proportional to that excitation. 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. Which of the following statements is true about Needle electrodes? Since deflection θ is proportional to the square of current through the coil, therefore scale of such instruments in non-uniform being crowded in the beginning.

They are designed to penetrate the skin so that they can record biopotentials like EEG signals from the brain. Show Explanation A photoconductor is a bulk semiconductor device, whose resistance varies when the light is incident on its surface. To practice all areas of IOT, here is complete set of 1000+ Multiple Choice Questions and Answers. Dec 31,2020 - Measurements And Instruments 1 MCQ | 20 Questions MCQ Test has questions of Electrical Engineering (EE) preparation. The area of the two parallel plates. Load cells typically contain multiple strain gauges aligned and wired in a Wheatstone bridge circuit. Thus applications of pyrometer are found in measuring the temperature of molten metals, the interiors of furnaces or the interiors of volcanoes. It can be linear or angular (rotational) motion. at the pressure below its vapor pressure can be used to measure temperature down to 1 K. The range can be increased to 600°C by filling the space above mercury with some inert gas. Photoconductive cell ANSWER: Mutual inductance 318. Same as a photovoltaic cell c) The saturation voltage V CE for silicon transistor is same as that for germanium.

In Preparation for the ECE Board Exam make sure to expose yourself and familiarize in each and every questions compiled here taken from various sources including but not limited to past Board Exam Questions in Electronics … Compression tension cells are used for measurement of a straight-line force ‘pushing together’ along a single axis; typically annotated as the negative force. 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. Lvdt Questions And Answers transducer mcqs with answers. High Output: The LVDT gives reasonably high output and hence requires less amplification.
