Parallel vs Series

If we add more light bulbs into a parallel circuit, how will the brightness of the bulbs change?

• It will get dimmer

• It will get brighter

• The brightness will stay the same

• None of the light bulb will be on

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.

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.

• The other bulbs will stay on

• The other bulbs will get dimmer.

• The battery will become stronger.

Are household appliances connected in series or parallel?

• Series

• Parallel

• Both

• I am not sure

Look at this Christmas tree lights. Are they connected in series or parallel?

• Series

• Parallel

• Both

• I am not sure

Which one is the circuit diagram of this parallel circuit?

• 
• 
• 
• 

Look at this picture of parallel circuit. If one of the light bulb breaks, what will happen to the other light bulb?

• The other light bulb will still on

• The other light bulb will be off

• Both lights will be off

• None of the light will be off

In parallel circuit, the current must split. This means when the ____ reach where the wire splits, the current will travel down one path or the other.

• Neutrons

• Protons

• Neurons

• Electrons
