A zero to 300 V voltmeter has guaranteed accuracy of 1% full scale reading. The voltage measured by the instrument is 83V. The percent limiting error is ___________
-
- 3.62
- 3.25
- 3.85
- 3.66
Correct Option: A
1% accuracy means that a maximum possible error of
| = 3 | ||
| 100 |
may be present in any reading. Since the deflection is 83V, therefore percent limiting error
| = | × 100 = 3.62 | |
| 83 |
