Concept 2 Review: Current

The flow of electric charges through a conductor is called

• electric current

• direct current

• alternating current

Which word means how hard it is for electrons to flow?

• Current
• Voltage
• Resistance
• Power

If the Voltage is increased and the resistance stays the same, Current will

• Increase
• Decrease
• Stay the same
• Not enough info

If the Voltage stays the same and Resistance is increased, Current will 

• Increase
• Decrease
• Stay the same
• Not enough info

What is current measured in?
