In Science we have been learning about electrical circuits. We built series and parallel circuits in a recent lab and explored removing a bulb from each to observe what would happen.
We learned that in a series circuit, if one bulb burns out or is missing, then the circuit will open and none of the lights will remain lit. This is because there is only one path for electric current to flow with this kind of circuit.
We also learned that any bulb in the path of a series circuit receives the same amount of electrical current. With parallel circuits, on the other hand, there is more than one path for electrical current to flow. Therefore, if one bulb burns out, the other bulbs will still remain lit. What fun!!
