engineering recuitment UPCL AE (E&M) 2021 Mock Test Electrical and Electronics Measurements Error Analysis
A zero to 300 V voltmeter has an error of 1.2% on full scale deflection. If the true voltage is 30 V then the range of readings on this voltmeter will be:
1
26.4 V to 33.6 V
2
20 V to 40 V
3
24 V to 36 V
4
29.4 V to 30.6 V
