Essential Question: How do I explain direct current electrical circuits?
Instructions: Study pp. 450-452 and answer the following questions
series circuit
In a
electricity has only one path to follow. All parts are connected one after
another. Electrons flow from the negative side of the battery around in a loop to the positive
side.
Draw arrows to show the path of the electricity in this series circuit.
If a light bulb is missing or broken in a series circuit, will the other bulb light? Explain.

parallel circuit
In a
, electricity has more than one path to follow. Electrons can follow different
paths as they flow from the negative side of the battery to the positive side.
Draw arrows to show the different paths electrons can travel in this parallel circuit.
If a light bulb is missing or broken in a parallel circuit, will the other bulb light? Explain.

because the path the electricity needs to follow is broken.
Yes because the electricity can travel along
a different path and avoid the broken bulb.
