A 0 - 10 A ammeter has a guaranted accuracy of 1.5% of full scale reading. The current measured by the instrument is 2.5 A. The percentage limiting error in the measurement is $\pm$ ________ %

Q. A (0 - 40)A ammeter has a guaranteed accuracy error of 2% of the full scale reading. If the current measured by this instrument is 10 A, the value of relative limiting error in percentage will be

Q. A variable w is related to three other variables $x,y,z$ as $w=xy/z$. The variables are measured with meters of accuracy $\pm 0.5$% reading, $\pm 1$% of full scale value and $\pm 1.5$% 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 limiting error in the measurement of $w$ will be

Q. An ammeter has a range of 0 to 30 A. The instrument gave the following readings.
$\begin{array}{ccccccc}\text{Current flow (A)}& 0& 5& 10& 15& 20& 25\\ \text{Ammeter reading}& 1& 4& 12& 14& 22& 28\end{array}$

The non-linearity of the instrument in terms of full scale reading (FSR) is ........ % FSR.

Q. A thermometer has $50$ uniform divisions & full scale reading is ${200}^{o}C$ with $\frac{1}{10}th$ of scale division estimated with accuracy. The resolution of the instrument in ${}^{o}C$ is

Q. Four students measured the reading by observing the position of pointer on the ammeter scale as shown below:



Assuming that the ammeter has no zero error, the correct reading is :
(1) 1.25 A
(2) 1.30 A
(3) 1.15 A
(4) 1.1 A
