Measurement and Instrumentation A set of independent current measurements taken by four observers was recorded as : 117.02 mA, 117.11 mA, 117.08 mA and 117.03 mA. What is the range of error ? ± 0.045 ± 0.056 ± 0.054 ± 0.065 ± 0.045 ± 0.056 ± 0.054 ± 0.065 ANSWER DOWNLOAD EXAMIANS APP
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 ± 7% ± 5% ± 8% ± 6% ± 7% ± 5% ± 8% ± 6% ANSWER DOWNLOAD EXAMIANS APP

Measurement and Instrumentation The total current I = I1 + I2 in a circuit is measured I1 = 150 ± 3A , I2 = 250 ± 4 A, where the limits of error are given as standard deviations. I is measured as (400 ±5) A (400 ± 1) A (400 ± 3) A (400 ± 2.24) A (400 ±5) A (400 ± 1) A (400 ± 3) A (400 ± 2.24) A 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 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 true but R is false A is false bur R is true 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 true but R is false A is false bur R is true ANSWER DOWNLOAD EXAMIANS APP
