Electricity

The flow of electricity in a circuit-

• current
• flow
• circuit

Electricity that flows in a closed path is called a

• path
• current
• circuit

To complete a circuit the switch must be

• unattached
• open
• closed

What is the major difference between static electricity and current electricity?

• Current electricity involves a continuous flow of neutrons; static electricity is a sudden transfer of protons
• Current electricity can be deadly; static electricity is almost always safe
• In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons
• Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons

This is an example of a _______ circuit

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

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
