Understanding Electrical Switches

What is the primary function of a switch in an electrical circuit?

• To increase the voltage

• To break and complete the circuit

• To reduce the current

• To change the direction of the current

Which materials are used to create a simple switch in the demonstration?

• Drawing pins and a paperclip

• Plastic and string

• Wood and nails

• Paper and glue

What role does the rubber play in the homemade switch?

• It increases the current

• It decreases the voltage

• It insulates and holds the drawing pins

• It conducts electricity

How does a household switch differ from the homemade switch demonstrated?

• It is smaller and uses less electricity

• It uses different materials but works the same way

• It is larger and uses more electricity

• It is more complex and works differently

What happens when a switch is closed in a circuit?

• The light bulb turns off

• The circuit is broken

• The current stops flowing

• The circuit is completed and the light bulb turns on
