Electrical Circuits Worksheet

In a simple circuit, which of these is NOT one of the main parts?

• Battery

• Wires

• Switch

• Something that uses power

Why does a series circuit stop working when one light bulb burns out?

• The battery is empty

• The wires get too hot

• The path for electricity is broken

• The other bulbs use too much power

Which of the following is a conductor?

• Rubber

• Wood

• Metal

• Plastic

What does an insulator do?

• Makes electricity stronger

• Speeds up electricity

• Stops electricity from flowing

• Stores electricity

Why is it helpful to have a switch in a circuit?

• It makes the circuit stronger

• It lowers battery power

• It lets us control when electricity flows

• It protects the wires

Which would NOT stop electricity from flowing?

• Plastic ruler

• Copper wire

• Rubber band

• Wooden stick

What happens when you add more batteries to a circuit?

• The current gets weaker

• The power gets stronger

• The circuit stops working

• The wires get colder

Suppose you are asked to explain to a friend why it is dangerous to touch a bare wire connected to a battery. What would you say?

• The wire is cold

• The wire is a conductor and can let electricity flow through your body, causing a shock

• The wire is heavy

• The wire is colorful

Suppose you observe that after rubbing a balloon on your sweater, it can pick up small pieces of paper. What reasoning best explains this effect?

• The balloon has become sticky due to sweat.

• The balloon has gained a static charge, which attracts the neutral paper pieces.

• The balloon is heavier than the paper.

• The balloon is colder than the paper.
