The heat generated in a wire depends on the resistance, current and time. If the error in measuring the above are 1 %, 2 % and 1 % , respectively, the maximum error in measuring the heat is

Options

  1. A8 %
  2. B6 %
  3. C18 %
  4. D12 %

Correct answer

B. 6 %

Step-by-step solution

aligned & H=i^2 R t & % error in H=2( % error in i)+( % error in R)+( % & error in t) & =2(2) %+1 %+1 %=6 % aligned
