Q. The $V - i$ graph for a good conductor makes angle $40{^\circ}$ with $V -$axis. Here $V$ denotes voltage and $i$ denotes current. The resistance of the conductor will be
A) $\sin{40{^\circ}}$
B) $\cos{40{^\circ}}$
C) $\tan{40{^\circ}}$
D) $\cot{40{^\circ}}$
Explanation
(d) Resistance, $R = \frac{V}{i} = \cot{40{^\circ}}$
