____________ allows electricity to flow.

• A conductor
• An insulator
• A magnet

The difference in electrical potential energy between two places is called

• resistance
• friction
• induction
• voltage

difference between ohmic and non-ohmic conductors is 

• ohmic conductor have constant resistance when the voltage is varied across them and non ohmic have changing resistance 
• resistance differs but temparature remain the same 
• no difference
• not enough information provided 

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

A non-ohmic conductor has a resistance that

• stays the same

• changes

Which of these describe a current-voltage graph for a lamp (non-ohmic)

• Straight line through the origin

• A curved line showing resistance changes

• A gradient that changes
