Why is there a difference in how bright the light bulbs are when we connect light bulbs in a series versus parallel?
If the two bulbs are in parallel, the electrons only have to go through one light
bulb, so there is less resistance.
The extra wire in the parallel circuit makes it easier for electricity to flow.
The electrons move more slowly in a parallel circuit due to the extra wire.
If there are two light bulbs in series, there is less resistance, so the electrons
move faster.
