Current and Static Electricity

A material in which electrons are able to move easily

• Circuit

• Insulator 

• Resistance 

• Conductor 

A complete, unbroken path that charges can flow through is called an __________________.

• conductor

• electric circuit

• electric current

• insulator

Why is static electricity not useful as a power source?

• Because electrons aren't transferred in burst of static electricity.

• Because ALL energy is released at once in static electricity.

• Because static electricity is not a real form of electricity.

• Because static electricity only occurs in lightening.

What is a Parallel circuit? 

• Has only one path 

• Has more than one path 

• Allows energy to travel through easily 

• Has only one light bulb

In a parallel circuit if one of the light bulbs burns out the rest _________.

• stop the flow of electricity

•  can still light up

•  will go out

• of the light bulbs burn out also

What might happen if wires weren't insulated?

• The power source would no longer provide a source of electrons.

• We'd be in danger of harm from electric shocks.

• Current electricity would become static electricity.

• The circuit would be broken.

What is the function of a power source in a circuit?

• It provides a steady source of static electricity.

• It provides a way for the circuit to be broken.

• It provides a path along which the electricity can flow.

• It provides a steady flow of electrons.

What is the unit of electric current?

• Ampere

• Volt

• Ohm

• Watt

Which of the following materials is a good conductor of electricity?

• Rubber

• Glass

• Copper

• Wood
