When a "dry-cell" flashlight battery with an internal resistance of 0.24 Ω is connected to a 1.65-Ω light bulb, the bulb shines dimly. However, when a lead-acid "wet-cell" battery with an internal resistance of 0.068 Ω is connected, the bulb is noticeably brighter. Both batteries have the same emf. Find the ratio Pwet/Pdry of the power delivered to the bulb by the wet-cell battery to that delivered by the dry-cell battery.
