How do you think the brightness of two lamps arranged in parallel compares with the brightness of two lamps arranged in series (Both arrangements having one cell)?

Solution

In parallel, both the bulbs will have the same voltage across them as that of the battery. However, in series connection, the voltage gets divided between the two bulbs. So, the bulbs which are connected in parallel will glow brighter.
