The flow of electric charges is 

• voltage
• current 
• resistance
• electricity 

A closed path that electric current flows is a

• circuit
• series circuit
• parallel circuit

What does a resistor do? 

• Reduces the flow of electrons
• Reduce the flow of the current
• Increase flow of electrons
• Decreases the flow of electrons 

Which way do electrons flow?

• Positive to Negative
• Negative to Positive

Where do electrons pick up their energy from? 

• Battery
• wire
• Lightbulb

Which of the following is not a source of electricity

• Amperes
• Volts

What it the formula to find voltage. 

• I= V/R
• R=V/I
