The measured value of resistance is 105Ω and its true value is 100Ω. The relative percentage error will be:
-
- 5%
- 10%
- 2·5%
- None of these
- 5%
Correct Option: A
Given, Measured value = 105Ω
True value = 100Ω
= Measured value – True value
Absolute error, δA = 105 – 100 = 5
| Relative error = | |
| true value |
or
| Relative error = | = | = 0.05 | ||
| A | 100 |
Percentage error = 5%
