Circuit Concepts

What is an open circuit?

• A circuit that has a continuous path for current flow.

• A circuit that has a high resistance.

• A circuit that has a short circuit.

• A circuit that has a break or gap in the path of current flow.

What is a closed circuit?

• A closed circuit is a complete and unbroken path for an electric current to flow.

• A closed circuit is a path that is open and does not allow any electric current to flow.

• A closed circuit is a path that only allows alternating current to flow.

• A closed circuit is a path that is partially broken, allowing some electric current to flow.

What is an incomplete circuit?

• A circuit that is not fully connected

• A circuit that is too complex to understand.

• A circuit that is broken or disconnected.

• A circuit that is not necessary for the functioning of a device.

Which type of circuit allows the flow of electric current?

• open circuit

• parallel circuit

• series circuit

• closed circuit

Which type of circuit does not allow the flow of electric current?

• Parallel circuit

• Open circuit

• Closed circuit

• Series circuit

What happens to a light bulb in an open circuit?

• The light bulb does not light up.

• The light bulb flickers on and off.

• The light bulb emits a dim light.

• The light bulb explodes.

What happens to a light bulb in a closed circuit?

• The light bulb will turn off.

• The light bulb will explode.

• The light bulb will emit smoke.

• The light bulb will light up.

What happens to a light bulb in an incomplete circuit?

• The light bulb will not light up.

• The light bulb will emit a dim light.

• The light bulb will explode.

• The light bulb will flicker.

How can you make an open circuit into a closed circuit?

• By adding an insulating material to the open circuit

• By increasing the resistance in the open circuit

• By removing the switch or disconnecting the two ends of the open circuit

• By closing the switch or connecting the two ends of the open circuit with a conducting material or wire.

How can you make an incomplete circuit into a closed circuit?

• Remove the loose ends from the circuit.

• Connect the loose ends with a conducting material or wire.

• Use an insulating material to cover the loose ends.

• Increase the voltage in the circuit.
