The potential difference across the ends of a conductor is (50 3) V and the current through it is (5 0.1) A . The percentage error in the measurement of resistance of the conductor is

Options

  1. A2
  2. B4
  3. C8
  4. D6

Correct answer

B. 4

Step-by-step solution

Given, V+ V=(50 3) V I + I =(5 0.1) A from ohm's law aligned & V=I R & V= I+ R & V V = I I + R R & R R = V V + I I = 3 50 - 0.1 5 & | R R | 100= 4 100 100=4 % aligned
