Which word best describes electricity as it occurs in nature?

• Orderly

• Stationary

• Sudden

• Powerless

Why is static electricity not useful as a power source?

• Because electrons aren't transferred in bursts 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 lightning

What is a current?

• A short burst of electricity

• A steady flow of electricity

• A wire along which electricity flows

• A power source that supplies electricity

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

• It provides a steady source of static electricity

• It provides a means through which the circuit can be broken

• It provides a path along which the electricity can flow

• It provides a steady flow of electrons

How does rubber differ from most metals?

• Rubber is a good conductor, most metals are good insulators

• Rubber conducts electrons; most metals conduct protons

• Rubber is a good insulator; most metals are good conductors

• Rubber is a good power source; most metals are good conductors

What might happen if wires weren't insulated?

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

• We would be in danger of harm from electric shocks

• Current electricity would become static electricity

• The circuit would be broken

Which of the following is an example of a load?

• 
• 
• 
• 

What device opens and closes an electric circuit?

• A switch

• A power source

• A load

• A current

What happens if you disconnect a circuit from its positive terminal

• Nothing happens

• The current reverses direction

• The electrons shoot out from the negative terminal

• The electrons stop flowing, and the current stops
