Lesson 3 Simple Circuits

Which of the following components is NOT part of a simple electric circuit?

• A source of electric energy
• An electric device
• An electric conductor
• A resistor

Which of the following components is essential for the flow of electric current in a simple circuit?

• A capacitor
• A switch
• An electric device
• An electric conductor

What is the significance of electric conductors in a circuit?

• They measure voltage levels
• They allow the flow of electric current
• They store electric energy
• They convert energy into light

What happens in a circuit when it is described as 'closed'?

• Energy is not flowing
• The circuit is incomplete
• The circuit is disconnected
• Energy flows through the circuit

Which statement accurately describes electric current?

• It is the resistance encountered by electric flow.
• It is the movement of electrically charged particles.
• It is the flow of electrons only.
• It is the measure of voltage in a circuit.

What role does a battery play in an electric circuit?

• It acts as a conductor
• It serves as a source of electric energy
• It converts energy into heat
• It measures voltage

How is electric current defined in the context of charged particles?

• The movement of electrically charged particles
• The resistance in a circuit
• The speed of electrical devices
• The flow of electrons only

What is the relationship between voltage and the amount of energy transferred in a circuit?

• Voltage only affects current, not energy.
• Voltage has no relation to energy transfer.
• Higher voltage means less energy is transferred.
• Higher voltage means more energy is transferred.
