GATE Instrumentation Engineering Practice Quiz

Question 1

A voltmeter has a specified accuracy of ±1% of full-scale reading and a full-scale value of 300 V. If it indicates 150 V, what is the maximum possible percentage error with respect to the indicated reading?

Accepted Answer

±2%

Question 2

The measured value of a resistance is 100 Ω with a possible absolute error of ±0.5 Ω. What is the relative error?

Accepted Answer

0.5%

Question 3

A quantity is computed as Q = x^2 y^3 / z. If the limiting errors in x, y, and z are ±1%, ±2%, and ±1% respectively, what is the maximum limiting error in Q?

Accepted Answer

±9%

Question 4

A moving-coil ammeter has a true current of 10 A flowing, but it indicates 9.8 A due to a constant negative bias. If 100 independent readings are averaged, assuming negligible random error, the average reading will be approximately

Accepted Answer

9.8 A

Question 5

A current I is computed from I = V/R. If the measured voltage has a limiting error of ±2% and the measured resistance has a limiting error of ±1%, what is the maximum limiting error in I?

Accepted Answer

±3%
