Electric To

What does lightning have in common with the shock you receive when you touch a doorknob?

• They both involve protons being pulled away from atoms.

• They're both forms of static electricity.

• They're both forms of current electricity.

• Neither of them has anything to do with electricity.

What causes the shock you receive when you touch a doorknob?

• Electrons being pulled from one surface to another.

• Protons being pulled from one surface to another.

• Neutrons being pulled from one surface to another.

• Positrons being pulled from one surface to another.

What causes lightning?

• A similarity in electrical charge.

• Electrons flowing through a conductor.

• A difference in electrical charge.

• Raindrops conducting electricity from the clouds to the ground.

A flow of electrons through a conductor is called:

• A river.

• A spark.

• An electron flow.

• A current.

In most electrical circuits, the pathway is made of:

• Metal

• Plastic

• Static

• Wood

What are the three components of a circuit?

• Pathway, source, and battery.

• Energy source, conductor, and receiver.

• Battery, bulb, and plastic.

• Wire, electron, and charge.

What is a common energy source for a circuit?

• A battery.

• A bulb.

• A wire.

• An appliance.

In the following diagram, the light bulb is:

• The pathway.

• The energy source.

• The conductor.

• The energy receiver.

What happens when electricity flows through an object?

• A magnetic field is destroyed.

• Protons are pulled away from their atoms.

• A magnetic field is created.

• Electrical charge is equalized.
