In a parallel circuit, there are several paths for the electrons to flow. If there are several bulbs in this type of circuit, if one goes out, the rest of the bulbs stay on. The bulbs in this type of circuit burn brighter because all bulbs receive the same amount of battery.
This is because each bulb in a parallel circuit has its own direct connection to the battery, so if one bulb goes out, the others can still receive power and continue to light up. Additionally, each bulb only has to resist the flow of a portion of the total current, so they can burn brighter with the same battery voltage compared to a series circuit where the current flow is the same through all bulbs.
