Hey guys, I've just starting learning about electric circuits at school and there's something I just can't seem to get my head around.
If you have two identical light bulbs in a series connected to a battery, the brightness of both the bulbs is the same. However, both bulbs are dimmer than if you simply had one light bulb in the series. I don't understand why both bulbs would be the same. It seems logical to me that the one closest to the battery would be brighter (electrons use all of their energy on that bulb) and the second bulb would be dimmer. However, this isn't the case. It is as if the electrons know that there is going to be another bulb up ahead, so they conserve half of their energy for it. How is this possible?
Thanks :)
