Measurement and Instrumentation Question & Answers June 9, 2021 By admin This article lists 100+ Measurement and Instrumentation MCQs for engineering students. All the Measurement and Instrumentation Questions & Answers given below includes solution and link wherever possible to the relevant topic. The measurement is the act or the result of a comparison between an unknown quantity and a known quantity. It is the process by which one can convert physical parameters to meaning full numbers. The measurement and instrumentation used in Home, Road vehicles, and Industry applications. The measurement is performed by using the instrument and the instrument used to do the measurements that are called a measuring instrument. The ruler, stopwatch, thermometer, weight machine, etc are the types of measuring instruments. The measurand is a physical parameter or variable to be a measure. There are seven types of methods of measurement are there they are direct, indirect, comparative, coincidence, contact, deflection, complementary methods. The ruler, thermometer, stopwatch are the measuring instruments. The result of the measurements contains two parts they are unit of measurement and number. In a direct measurement method, the unknown quantity (measurand) is measured directly instead of comparing it with a standard. The measurement of current using an ammeter, measurement of voltage using a voltmeter, measurement of resistance using an ammeter are examples of direct measurement methods. 1). ____________ is a physical parameter or variable to be a measure Measurand Standard Both a and b None of the above Hint 2). ________ is defined as a quantity of the same kind chosen as a unit or basis for comparison of a quantitative value to be a measure Measurand Standard Both a and b None of the above Hint 3).
