Electricity that flows in a closed path is called a

• path
• current
• circuit
• light

A naturally occurring force that exists all around us is called _________.

• Magnetism
• Electricity
• Electrica
• Electrical current.

Any material that does not allow electrical energy to pass through (ex. plastic, glass, paper, cardboard)

• conductor
• device
• insulator

Allows electrical current to flow through an electric circuit (ex. copper wire).

• insulator
• conductor
• resistor (device)

Whats units are used to measure electric currents?

• volts
• Newtons
• grams

How does alternating current differ from direct current?

• Alternating current produces more voltage than direct current.

• Alternating current always flows in the same direction; the direction of a direct current switches back and forth.

• Direct current produces more voltage than alternating current.

• Direct current always flows in the same direction; the direction of an alternating current switches back and forth.

Electric current that flows in only one direction. 

• Voltage 
• Direct Current 
• Alternating Current
• Series Circuit 

Electric current that reverses its direction of flow in a regular pattern  

• Voltage 
• Direct Current 
• Alternating Current 
• Parallel Circuit
