QB_PH_030: Mathematical Physics - Module 4

Question Statement

Resistance $R = V / I$. If $V = 100 \pm 2\text{ V}$ and $I = 10 \pm 0.1\text{ A}$, the percentage error in $R$ is $\pm X\%$. What is $X$?
Correct Answer
3, 3
Verified Key

Step-by-Step KaTeX Derivation & Detailed Explanation

### Solution: $\Delta R / R = \Delta V / V + \Delta I / I = 2/100 + 0.1/10 = 0.03 = 3\%$.
