Resistance and Percentage Error
This interactive simulation demonstrates how to calculate percentage error in resistance using Ohm's Law (R = V/I), based on Example 2.9 from Physics textbooks.

R
R = V / I
Percentage error in R = (ΔV/V) × 100 + (ΔI/I) × 100
Percentage error in R = (ΔV/V) × 100 + (ΔI/I) × 100
Calculation Results
Example 2.9 Solution:
Given V = (100 ± 5)V and I = (10 ± 0.2)A
Percentage error in V = (5/100) × 100 = 5%
Percentage error in I = (0.2/10) × 100 = 2%
Therefore, percentage error in R = 5% + 2% = 7%
