Question

The resistance R = V I , where V = 50 ± 2 V and I = 20 ± 0 . 2 A . The percentage error in R is x % . The value of x to the nearest integer is ________.,

MARKS App · Accepted Answer

Δ R R × 100 = Δ V V × 100 + Δ I I × 100 % error in R = 2 50 × 100 + 0 . 2 20 × 100 % error in R = 4 + 1 % error in R = 5 %
