Which electric circuit contains several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

This circuit has a battery, buzzer, and switch. When the switch is turned on, the buzzer will produce sound because -

• The turned on switch will provide energy to the buzzer.

• The turned on switch will decrease the resistance in the circuit.

• Electrical energy will be absorbed completely by the buzzer when the switch is turned on.

• Electric charges will flow in a complete path when the switch is turned on.

Choose the correct sentence.

• This circuit will work because it is an open circuit.

• This circuit will work because it is a closed circuit.

• This circuit will NOT work because it is an open circuit.

• This circuit will NOT work because it is a closed circuit.
