TS EAMCET · Physics · Current Electricity
Current flowing through a circuit is shown in the figure then the resistance of the circuit is
- A cannot be determined
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
From the above graph between current and potential difference, we can get the slope of the graph, tanθ and we know that the tanθ=perpendicular base=∆I∆V=1R, here R is the resistance, it means, R=1tanθ=1tan60°=13 Ω.
