Electricity

The student conducted an experiment with circuits. Why was the bulb bright when he closed the switch?

• The switch produced an electric current

• Closing the switch broke the circuit

• Closing the switch completed the circuit

• The switch did not make a difference

In a parallel circuit the current

• makes one circle
• stays in one path
• splits and goes through two components

Two types of circuits are

• parallel and magnetic
• electromagnetic and series
• series and parallel

The flow of electricity requires a

• complete path
• incomplete path
• insulated current

What is an insulator?

• The area of a conductor through which a current is able to move
• A material which does not allow electricity to go through it
• The amount of devices which are in a circuit
• A battery or other device which provides energy for a circuit
