Explanation:
Electric devices can be connected into two types of configuration:
- Series: two devices are connected in series if they are along the same branch. In this case, the current flowing through the two devices is the same (but the potential difference across them is different)
- Parallel: two devices are connected in parallel if they are along two different branches that are connected to the same ends. In this case, the current flowing through the two devices is different, while the potential difference across them is the same.
The figure attached shows a circuit in which:
- The first 2 light bulbs on top are connected in parallel
- Then these 2 bulbs are connected in series to the light bulb on bottom
