✔ 最佳答案
二個相同燈泡串聯接二個相同電池串聯亮度和一個燈泡接一個電池(燈泡和電池都相同)的亮度那一個較亮?應該都沒有兩樣吧！

如果是兩顆電阻，那應該是沒差!
但問的是燈泡，理想上會一樣亮!
但實際上會不會因為燈泡的不一致，
而使亮度不一樣，這就不能確定了!

when you connect two batteries in serial, it will double its voltage. Therefore, you need to make sure that the light bulb you use to do the test can be used for one battery or two batteries.

If they can be used for both types, then two batteries will be brighter, due to higher voltage.
