Electricity

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 are both forms of static electricity

• They are both forms of current electricity

• Neither of them have 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 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

What would a lightbulb be in a circuit?

• 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

What are the two poles of a magnet called?

• Up and down

• East and west

• Left and right

• North and south
