What is an electric circuit?

• An electric circuit is a device that converts electrical energy into mechanical energy.
• An electric circuit is a type of battery used to store electrical energy.
• An electric circuit is a network of wires used to transmit data.
• An electric circuit is a closed loop or pathway that allows electric current to flow through it.

Which component of an electric circuit is responsible for providing

• Power source
• Capacitor
• Switch
• Resistor

In an electric circuit, what is the role of conductors?

• Conductors allow the flow of electric current.
• Conductors block the flow of electric current.
• Conductors generate electric current.
• Conductors store electric current.

What does a switch do in an electric circuit?

• A switch in an electric circuit amplifies the electric current.
• A switch in an electric circuit generates electricity.
• A switch in an electric circuit regulates the voltage.
• A switch in an electric circuit opens or closes the circuit to control the flow of electric current.

In a series circuit, what happens if one component fails or is turned off?

• The other components will continue to function normally.
• The entire circuit will be broken and no current will flow.
• The circuit will automatically switch to a parallel configuration.
• The circuit will become overloaded and may cause a fire.

In a parallel circuit, what happens if one component fails or is turned off?

• The other components will function at a reduced capacity.
• The other components will overheat and cause a fire.
• The other components will also fail.
• The other components will continue to function normally.
