• voltage
• current 
• resistance
• electricity 

Which of the following is NOT an example of an insulator.

A closed path that electric current flows is a

• circuit
• series circuit
• parallel circuit

What does a resistor do? 

• Reduces the flow of electrons
• Controls the flow of the current

• Increase flow of electrons
• Decreases the flow of electrons 

What is the unit of measurement for current

• Ohm's
• Amperes
• Volts

What it the formula to find voltage. 

• I= V/R
• R=V/I
• V= I x R
