1160 - What are the effects of series and parallel connections for batteries and light bulbs?

Imagine you have some batteries and light bulbs to connect. There are two ways to do it: series and parallel. Here's how they work:

Series Connection: - Batteries: The voltage of the batteries adds up (more power), but if one battery runs out or breaks, all the batteries stop working. - Light Bulbs: If one bulb breaks, all the bulbs turn off. The voltage is the same for each bulb, but the bulbs get brighter as you add more batteries.

Parallel Connection: - Batteries: If one battery runs out or breaks, the other batteries keep working. But the total power doesn't increase as much as in series. - Light Bulbs: Each bulb works independently. If one bulb breaks, the other bulbs stay on, and they are all equally bright.

Think of it like a row of books (series) and a group of tables with books on each one (parallel). In a row of books, if you remove one book, the whole row is affected. But if you remove a book from one table, the other tables with books are still fine.
