Measurement and Instrumentation A variable w is related to three other variables x, y and z as w = xy/z. The variables are measured with meters of accuracy ± 0.5% reading, ± 1% of full scale value and ± 1.5% reading. The actual readings of the three meters are 80, 20 and 50 with 100 being the full scale value for all three. The maximum uncertainty in the measurement of w will be ± 6% ± 5% ± 7% ± 8% ± 6% ± 5% ± 7% ± 8% ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Assertion (A) : It is always desirable to take the reading of an indicating instrument very close to the full scale reading. Reason (R) : Accuracy of an indicating instrument is maximum at the full scale deflection and error increases as reading comes closer to the beginning of the scale. Both A and R are true and R is the correct explanation of A A is false bur R is true A is true but R is false Both A and R are true but R is NOT the correct explanation of A Both A and R are true and R is the correct explanation of A A is false bur R is true A is true but R is false Both A and R are true but R is NOT the correct explanation of A ANSWER DOWNLOAD EXAMIANS APP
