Electrical Circuits Quiz

What is an electrical circuit?

• A power source that provides electricity

• A device that uses electricity to create light

• A path made of wires that allows electrons to flow and create electricity

• A switch that controls the flow of electricity

What is the purpose of a battery in an electric circuit?

• To provide the force (voltage) that makes electrons move

• To connect the wires and devices in the circuit

• To control the flow of electricity

• To create light

What is an electric current?

• The device that uses electricity to create light

• The path made of wires in an electrical circuit

• The force that makes electrons move

• The movement of electricity that flows through a circuit to provide power to devices

What happens in an open circuit?

• One of the wires becomes unattached, so current cannot flow

• Current can move from a battery through the wires and devices

• The lights turn on

• The switch is off

What is the purpose of a switch in a circuit?

• To provide the force (voltage) that makes electrons move

• To turn the circuit on or off by closing or opening the gap

• To connect the wires and devices in the circuit

• To create light

What is a series circuit?

• A circuit where electricity has only one path to follow

• A circuit where electricity has multiple pathways to follow

• A circuit where the lights stay bright no matter how many lightbulbs are added

• A circuit where the lights become dimmer as more bulbs are added

What happens in a parallel circuit if a light bulb burns out?

• Only the light bulb that burns out goes dark, the rest stay lit

• All the light bulbs go dark

• The circuit becomes incomplete and the current stops flowing

• The lights become brighter

What is the purpose of a circuit diagram?

• To create light

• To connect the wires and devices in the circuit

• To turn the circuit on or off by closing or opening the gap

• To use circuit symbols instead of drawing each component in the circuit

What are conductors?

• Materials that let electricity pass through them easily

• Materials that do not allow electricity to pass through them

• Materials that create light when electricity flows through them

• Materials that control the flow of electricity

What are insulators?

• Materials that create light when electricity flows through them

• Materials that let electricity pass through them easily

• Materials that do not allow electricity to pass through them

• Materials that control the flow of electricity
