Electricity Introduction

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

Which of these materials is a good conductor of electricity?

• Rubber

• Metal

• Newspaper

• Glass

Why do electricians always wrap wires in plastic?

• Plastic comes in many different colors

• Plastic is a good electrical conductor

• Plastic makes the wires easy to bend

• Plastic is a good electrical insulator

which of the following materials are best used as insulators?

• Wood

• Rubber

• Metal

A science class was completing an experiment on electrical circuits. Why did the bulb go out each time the switch was opened?

• Opening the switch broke the circuit

• The battery was probably going flat

• There was too much electricity flowing

• Opening the switch closed the circuit

A/an _________________ is an object that will allow electricity to flow through it.
