Question

The voltage applied across the resistance R is 200+5 and current in resistance is 20+0.2 then find % error in resistance.

• A. 3.5 %
• B. 5 %
• C. 7 %
• D. 3 %

Answer 1

The Correct Option is A

\(V= RI\)

\(R=\frac{V}{I}\)

\(\frac{5}{200}\times100\%+\frac{0.2}{20}\times100\%\)

\(3.5\%\)

\(\text{The Correct option is (A):}\) \(3.5 \%\)
