Series or parallel?

Jane hosted a party in her house but, unfortunately, the fuse has blown. She has an ideal battery (with zero resistance) and two bulbs. To produce a greater brightness (greater total power by the bulbs), should she connect the bulbs in series or in parallel with the battery?

Note:

• The equivalent resistance $$(R_{\text{net}})$$ of two resistors $$R_1$$ and $$R_2$$ in series is $$R_1+R_2,$$ and in parallel $$\frac{R_1R_2}{R_1+R_2}$$.
• The power produced in a circuit is $$\frac{V^2}{R_{\text{net}}}$$ or $$i^2 R_{\text{net}}$$.
