Electricity, Conductors, and Insulators

What do you think conductors and insulators are?

What is the difference between a closed path and an open path in an electric circuit?

• A closed path has no resistance; an open path has high resistance.
• An open path allows current to flow; a closed path interrupts the flow.
• A closed path is always shorter than an open path.
• A closed path allows current to flow; an open path interrupts the flow.

what type of path did he create with this circuit system?

• Open circuit path
• Closed loop path
• Short circuit path
• Disconnected path

When the circuit was cut, what type of circuit was creates?

• Open circuit
• Closed circuit
• Short circuit
• Series circuit

Why did the light bulb turn on when the metal spoon was added to the circuit?

• The light bulb turned on due to a chemical reaction in the circuit.
• The light bulb turned on because the metal spoon is a conductor that completed the circuit, allowing electricity to flow.

• The light bulb turned on because the spoon was made of plastic.
• The light bulb turned on because the spoon was a conductor of heat.

During a lightning rain storm, should you be near or in a metal fence?

• Yes, it's safe to be near a metal fence.
• You should stand on the metal fence for protection.
• No, you should not be near or in a metal fence because lightning is attracted to metal and water.

• Being in a metal fence attracts lightning, but it's fine.

Where is the safest place to be during a lightning storm?

• Indoors in a well-constructed building.
• Near a body of water
• In an open field
• Under a tree

Why did the light bulb (output device) not turn on with the rubber ducky connected to the circuit system?

• The rubber ducky is an insulator and does not complete the circuit.

• The rubber ducky is a light bulb and should light up.
• The circuit is powered by a battery that is dead.
• The light bulb is broken and needs to be replaced.

What do insulators do?

• Insulators allow electricity to pass freely.
• Insulators prevent the flow of electricity and heat.
• Insulators are used to conduct heat efficiently.
• Insulators enhance the flow of electricity.

Name some insulating items that will protect you from electricity.

• Wooden mats
• Metal gloves
• Rubber gloves, plastic mats, insulating boots
• Cotton shoes
