1.

Is this Circuit series or parallel? Why?

a)

Series - It has 3 light bulbs.

b)

Series - Because it is one loop. The current only has one way to flow.

c)

Parallel - The electrical current is divided between the three light bulbs.

d)

Parallel - Because it is one loop.The current only has one way to flow.
