A and B are two points on a uniform ring of resistance R. The ∠ACB = θ, where C is the centre of the ring. The equivalent resistance between A and B is
\[R\frac{2\pi-\theta}{4\pi}\]
\[R\left( 1-\frac{\theta}{2\pi} \right)\]
\[R\frac{\theta}{2\pi}\]
\[\frac{R}{4\pi^{2}}\left( 2\pi-\theta \right)\theta\]
