Understanding Electrical Circuits

Which part of the circuit shows the power source?

• Resistor

• Switch

• Battery

• Wire

What part of the circuit controls the flow of electricity?

• Resistor

• Bulb

• Wire

• Switch

Which part of the circuit provides resistance?

• Battery

• Resistor

• Wire

• Switch

What is the path through which electricity flows?

• Conductor

• Circuit

• Resistor

• Magnet

Why is it more advisable to use a parallel circuit in household wiring?

• It allows electricity to flow in one path only.

• It ensures that when one appliance is off, others continue working.

• It prevents electricity from flowing.

• It makes the bulbs dimmer.

What happens to the brightness of the bulbs in a series circuit when more bulbs are added?

• They become brighter.

• They remain the same.

• They become dimmer.

• They explode.

Which material is the best conductor of electricity?

• Wood

• Gold

• Rubber

• Plastic

What happens when a bulb is removed from a series circuit?

• The other bulbs stay on.

• The circuit remains functional.

• The other bulbs go out.

• The power increases.

What is the difference between static electricity and current electricity?

• Static electricity flows continuously, while current electricity stays in one place.

• Static electricity is a sudden discharge, while current electricity flows through a conductor.

• They are both the same.

• Static electricity is stronger than current electricity.

Why does the light from a bulb go out when you turn off the switch?

• The switch produces electricity.

• The switch breaks the circuit.

• The switch increases the flow of electricity.

• The battery runs out immediately.
