Question

If absolute error is 1V and % error is 1.25% then Relative accuracy is_________

Answer 1

Given :- ∂A = 1 , εA = 1.25%

To find :- relative accuracy

Solution :-

• here we have to find limits of value

• A = ∂A ÷ εA × 100
• A = 1 ÷ 1.25 × 100
• A = 80
• So original value is A= 80
• Limits of value = A ± ∂A
• = 80 ± 1
• = 79 , 81

So accuracy is 79 , 81
