Open/Closed Circuits

What is an open circuit?

• A circuit that is complete and allows electricity to flow.

• A circuit that is not complete, meaning there is a break in the path for electricity to flow.

• A circuit that has a short circuit causing excess current flow.

• A circuit that is designed for high voltage applications.

What is a conductor?

• A material that allows electricity to flow through it easily, such as copper or aluminum.

• A material that prevents electricity from flowing, like rubber.

• A type of electrical device that stores energy, such as a battery.

• A component that converts electrical energy into mechanical energy, like a motor.

What is a closed circuit?

• A circuit that is open and does not allow electricity to flow.

• A complete circuit that allows electricity to flow uninterrupted.

• A circuit that only works with batteries.

• A circuit that has multiple paths for electricity to flow.

What is a complete circuit?

• A closed loop that allows electric current to flow from the power source, through the components, and back to the power source.

• A path that only allows current to flow in one direction.

• A circuit that has a break in it, preventing current from flowing.

• A type of circuit that only works with batteries.

What happens when a circuit is closed?

• Electricity flows freely, and devices connected to the circuit will operate.

• The circuit becomes open and electricity stops flowing.

• The circuit overheats and may cause a fire.

• Only some devices connected to the circuit will operate.

What is a parallel circuit?

• A type of circuit where electricity flows in a single path.

• A type of circuit where there are multiple paths for electricity to flow, so if one path is broken, others can still work.

• A circuit that only works when all components are connected in series.

• A circuit that uses a battery to store energy for later use.

What is resistance in a circuit?

• A measure of how much a component opposes the flow of electric current, affecting how much current flows in the circuit.

• The total amount of voltage in a circuit.

• The speed at which electric current flows through a conductor.

• The ability of a component to store electric charge.

What is an incomplete circuit?

• A circuit that has a break or gap, preventing electricity from flowing.

• A circuit that allows electricity to flow continuously.

• A circuit that is fully connected and operational.

• A circuit that only works with batteries.

What happens when a circuit is open?

• The flow of electricity continues, and devices work normally.

• The flow of electricity stops, and devices connected to the circuit will not work.

• The circuit becomes a short circuit, causing devices to malfunction.

• The circuit remains active, but devices may experience reduced power.

What type of energy does a battery provide to a circuit?

• Chemical energy

• Electrical energy

• Mechanical energy

• Thermal energy
