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

Answer: (A)

3.5 %

Answer 2

$V= RI$

$R=\frac{V}{I}$

$\frac{5}{200}\times100\%+\frac{0.2}{20}\times100\%$

$3.5\%$

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