The error in the measurement of resistance, when \((10 \pm 0.5)\) A current passing through it produces a potential difference of \((100 \pm 6) \mathrm{V}\) across it is
- A \(1 \%\)
- B \(5.5 \%\)
- C \(6.5 \%\)
- D \(11 \%\)
Answer & Solution
Correct Answer
(D) \(11 \%\)
Step-by-step Solution
Detailed explanation
Since \(R=\frac{V}{I}\) so, error in the measurement of resistance \(\frac{\Delta \mathrm{R}}{\mathrm{R}} \times 100=\frac{\Delta \mathrm{V}}{\mathrm{V}} \times 100+\frac{\Delta \mathrm{I}}{\mathrm{I}} \times 100\) Given current \(=(10 \pm 0.5) \mathrm{A}\) and potential…
