The potential difference across the ends of conductor is ( 30 0.3) V and the current through the conductor is (5 0.1) A . The error in the determination of the resistance of the conductor is

Options

  1. A1 %
  2. B2 %
  3. C3 %
  4. D4 %

Correct answer

C. 3 %

Step-by-step solution

V =(30 0.3) V , I =(5 0.1) A Resistance, R= V I aligned & R R = V ~V + I I = 0.3 30 + 0.1 5 =0.03 & % R = ( R R 100 )=0.03 100=3 % aligned
