If voltage \(V=(200 \pm 8) \mathrm{V}\) and current \(I=(20 \pm 05) \mathrm{A}\), then the percentage error in resistance \(R\) is
- A \(5.2 \%\)
- B \(25 \%\)
- C \(3 \%\)
- D \(6.5 \%\)
Answer & Solution
Correct Answer
(D) \(6.5 \%\)
Step-by-step Solution
Detailed explanation
Voltage, \(V=\langle 200 \pm 8) \mathrm{V}\) Current, \(I=(20 \pm 05) \mathrm{A}\) \(\therefore\) Fesistance, \(R=\frac{V}{I}=\frac{200}{20}=10 \Omega\) Taking maximum error condition,…
