The potential difference across two points is generally referred to as...

• Micrometer
• Voltage
• Amperage
• Resistance

Things that have almost NO resistance to electron flow are generally referred to as:

• Bad conductors of electricty
• Good conductors of electricty
• Superconductors
• Transistors

Which way do electrons flow?

• From negative to positive
• From positive to negative
• from negative to negative
• From positive to positive

What would happen if you took one bulb out of a series circuit?

• The circuit would be closed
• It would not change the circuit

What is static electricity?

• the flow of electric charges
• the build-up of an electrical charge on a surface.
• the opposition of current flow. 

What is the unit of measurement for resistance?

• Amperes
• Ohm's
• Volts

Voltage difference is related to the force that causes electric charges to flow. 

• True
• False

An example of an insulator is:

• iron
