# NEET Physics Current Electricity Questions Solved

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

(1) $\mathrm{sin}\theta$

(2) $\mathrm{cos}\theta$

(3) $\mathrm{tan}\theta$

(4) $\mathrm{cot}\theta$

(4) At an instant approach the student will choose tanθ will be the right answer. But it is to be seen here the curve makes the angle θ with the V-axis. So it makes an angle (90 – θ) with the i-axis.

So resistance = slope = tan (90 – θ) = cotθ.
