Add another load to one of your pathways. Notice the brightness of the two loads one pathway and the brightness of the single load in another pathway. What can you conclude about loads in different pathways in a parallel circuit opposed to loads in a series circuit?
In a parallel circuit, each load has its own pathway to the power source, allowing it to receive the full voltage. This results in each load operating at its full brightness independently of the other loads in the circuit. In contrast, in a series circuit, adding a load to a pathway causes the voltage to be divided among all the loads in that pathway, resulting in reduced brightness for all the loads in that pathway. Ultimately, this demonstrates that loads in different pathways in a parallel circuit operate independently and at full brightness, while loads in a series circuit share voltage and brightness is reduced as more loads are added.
