Vedclass · Answer

(D) According to Ohm's law,$V = iR$,so $R = V/i$.In the given graph,the $V$-axis is vertical and the $i$-axis is horizontal.The angle $	heta$ is given with the $V$-axis.Therefore,the slope of the graph with respect to the $i$-axis is $	an \phi$,where $\phi$ is the angle with the $i$-axis.Since $\phi = 90^\circ - 	heta$,the slope is $	an(90^\circ - 	heta) = \cot 	heta$.Since the slope of a $V-i$ graph represents resistance $R$,we have $R \propto \cot 	heta$.
