What is the aim of the battery in a circuit?

• It lights up

• It provides energy for the circuit

• It is an insulator that allows current to flow through

In a circuit, electrons:

• flow from the positive to the negative terminal

• carry energy around the circuit

• do not move at all

• flow from the negative to the positive terminal

Static electricity is created by

• Electrons flowing through a circuit

• Accumulation of heat

• Friction between objects

• The presence of batteries

What is the role of an insulator?

• Let the current flow easily

• Transform electricity into heat

• Prevent electrons from passing

• Increase the speed of electrons

Amongst these materials, which one is a good conductor:

• Plastic

• Wood

• Copper

• Glass

Why are pieces of paper attracted by a charged balloon?

• Because they are light

• Because of gravity

• Because they are electric

• Because they are attracted by the charged balloon

Lightning are a good example of:

• Static electricity

• Current electricity

• Heat process

• Electric curcuit

Why are electric wires protected by a plastic layer?

• To increase the speed of electrons

• To protect the user in case they touch them

• To increase the power

• To make the wires colorful and pretty
