Question

A 100 V voltmeter has full-scale accuracy of 5%. At its reading of 50 V it will give an error of

Answer 1

Answer:

10%

Explanation:

Limitting error=(Full sccale reading/Measured scale)*Accuracy at full scale

=(100/50)*5%=10%

Answer 2

Given,

Voltage of voltmeter=100v

Accuracy=5%

Reading is 50V

To Find,

Error of voltmeter

Solution,

Here full scale reading is=100V

Measured scale=50V

Accuracy at full scale=5%

So, it will give an error

=(Full scale reading/Measured scale)×Accuracy at full scale

=(100/50)×5%=10%

Hence, it will give an error of 10%.
