I am trying to show that for an affine algebraic set $V\subset K^n$ with $K$ algebraically closed, $$\operatorname{Shv}(V;\mathcal{C})\simeq\operatorname{Shv}(\operatorname{Spec}(\mathcal{O}_V);\mathcal{C}),$$ where $\mathcal{C}$ is any category.
I know that we have to find a fully faithful functor $F:\operatorname{Shv}(V;\mathcal{C})\to\operatorname{Shv}(\operatorname{Spec}(\mathcal{O}_V);\mathcal{C})$, but I am unable to figure out this functor. Can somebody please help me? And, please elaborate your statements.
