The V-i graph for a conductor makes an angle θ with V-axis. Here V denotes the voltage and i denotes current. The resistance of conductor is given by
Text Solution
Verified by ExpertsThe correct answer is:
D
At an instant approach the student will choose tan θ θ will be the right answer. But it is to be seen here the curve makes the angle θ θ with the V-axis.
So it makes an angle (90 – θ θ ) with the i-axis.
So resistance = slope = tan (90 – θ θ ) = cot θ θ .
