Body-Explanation

In a parallel circuit, all the branches in parallel receives the same amount of voltage. After finding the current, we found out that the lower ohm bulb used more current. This makes sense because the higher the resistance, the lower the current. This is proved by ohm's law.

However when finding the voltage, we found out that even though the light bulbs had different resistances, they still used the same amount of voltage. This is due to the fact that they are in parallel.
