Circuits Series and Parallel

What is a closed circuit?

• A pathway that allows one circuit to flow

• A pathway that does not allow an electric current to flow.

• A Parallel circuit.

• A pathway that allows an electric current to flow freely - light is on!

What is a Light Bulb in a circuit?

• The energy available to move charges through a circuit

• The device that provides electrical energy

• Rubber, styrofoam, cotton

• One of the parts of a circuit, when it is in a closed circuit it is lit

What is a wire in a circuit?

• One of the parts of a circuit that carries electrons from place to place

• The device that provides electrical energy

• The energy available to move charges through a circuit

• One of the parts of a circuit, when it is in a closed circuit it is lit

What is a Switch in a circuit?

• One of the parts of a circuit that carries electrons from place to place

• One of the parts of a circuit that carries electrons from place to place

• The device that provides electrical energy

• The device that opens and closes a circuit

If the switch was opened, what would happen?

• the ammeter would measure a current flowing

• current would no longer flow, so everything would be off

• the bulbs would stay on because they're connected to the cell

• the bulbs would burn out and catch fire

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.

This is an example of a _______ circuit

• open

• series

• parallel

• switch

As you continue to add lightbulbs in series, what happens?

• The bulbs get brighter

• The bulbs get dimmer

• The bulbs remain the same brightness

• The bulbs explode and shards of glass get everywhere

If one bulb goes out in a series circuit, the remaining bulbs...

• also go out

• get brighter

• get dimmer

• explode, leaving shards of glass everywhere
