DOL Series and Parallell Circuits

Part A: Which type of circuit is represented in the image below?

• Parallel Circuit

• Series Circuit

• Open Circuit

• None of the above

Part B: Explain how you know which type of circuit is represented in part a. 

Michael and Fabian build the circuit pictured below. How many light bulbs will be lit up if the top bulb is unscrewed?

• All the bulbs will turn off because it is a series circuit and the electrical current will not flow through.

• The other two bulbs will remain lit, because this is a parallel circuit and electricity will still flow through the other loops

• The other two bulbs will remain lit, because this is a series circuit and electricity will still flow through the other loops

• All the bulbs will turn off because it is a parallel circuit and the electrical current will not flow through.

Observe the circuit below. Trace the flow of electricity, IF switches B, C, and D are closed, but switch A is left open. How many bulbs will light up?

• 3

• 1

• 0

• 2

Multi Select: Adriana constructs the circuit below. With the switches in these positions, which lights are on?

• 1 and 2

• 2 and 4

• 3

• All of the bulbs

Which of the following explains the difference between parallel circuits and series circuits?

• Parallel circuits always work, even if the circuit is open. Series circuits only work when it is closed.

• Parallel circuit is a single path for an electrical current. Series circuit has multiple paths for electrical current.

• Series circuit is a single path for an electrical current. Parallel circuit has multiple paths for electrical current.

• Series circuits only work when the circuit is open. Parallel circuits only work when it is closed.
