हिन्दीThe resistance \( R = \frac{V}{I} \) where \( V = (100 \pm 5)\text{ V} \) and \( I = (10 \pm 0.2)\text{ A} \). The total percentage error in \( R \) is:
Correct answer · Option 3
\( 7\% \)
Explanation
\( \frac{\Delta R}{R}\% = \frac{\Delta V}{V}\% + \frac{\Delta I}{I}\% = \frac{5}{100} \times 100 + \frac{0.2}{10} \times 100 = 5\% + 2\% = 7\% \).
