Current flowing through a circuit is shown in the figure then the resistance of the circuit is

Options

  1. Acannot be determined
  2. B1 3 Ω
  3. C3 4 Ω
  4. D1 2 Ω

Correct answer

B. 1 3 Ω

Step-by-step solution

From the above graph between current and potential difference, we can get the slope of the graph, tan θ and we know that the tan θ = p e r p e n d i c u l a r   b a s e = ∆ I ∆ V = 1 R , here R is the resistance, it means, R = 1 tan θ = 1 tan 60 ° = 1 3   Ω .
