Electricity - Tree

Electricity always flows in what direction?

• From the negative end of the battery back to the negative end of the battery.
• From the negative end of the battery to the positive end of the battery.
• From the positive end of the battery to the negative end of the battery
• From the positive end of the battery back to the positive end of the battery.

What happens when unlike charges come in contact?

• The materials repel each other.
• The materials will start an electric current.
• Nothing will happen.
• The materials will attract each other.

An insulator is:

• A material that allows current to flow through it easily.
• The flow of electrons through a material.
• A material that does not allow current to flow through it easily.
• A circuit with more than one path.

What is voltage?

• A measure of how difficult it is for electrons to flow.
• A measure of the difference in electrical potential between objects that have opposite charges
• The continuous flow of electrons around a circuit.
• The fast, sudden movement of electrons from a negative to a positive material.

What is a parallel circuit?

• A circuit with only one path for the current to flow through.
• A circuit with more than one path for the current to flow through.
• A material that allows current to flow through easily.
• None of the above.

The flow of electrons around a circuit is called:

• Static Electricity
• An Open Circuit
• Parallel Electrons
• Current Electricity

In order for a light bulb to light:

• it must be part of an open circuit.
• it must be part of a closed circuit.
• it must have static electricity.
• all of the above.

A toaster or burner on an electric stove heats up by:

• creating resistance
• creating current
• static electricity
• static discharge

On a dry day, you are taking laundry out of the dryer and a sock clings to your shirt. This is an example of:

• current electricity
• repulsion
• static electricity/charge
• protons

The purpose of the filament in a light bulb is to:

• connect to the battery source
• serve as a conductor
• serve as a source of electrical power
• provide resistance so that it can get hot and glow
