Circuits

This is an example of a _______ circuit

• open
• series
• parallel
• square

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

What is the definition of electrical current?

• The opposition to the flow of electrons

• The rate of flow of charge

• The work done on each coulomb of charge

• Electrons moving around

Does this statement best describe a parallel or a series circuit.
 
When more light bulbs are added they all remain bright. 

• Parallel circuit
• Series circuit

Parallel circuits are

• a circuit that has only one path for current to travel
• has more than one path for current to travel
• a circuit that does not allow electricity to travel through it
• magnets that cause electric current
