Electrical Safety

What is a short circuit?

• A circuit that has a longer path than intended

• A circuit that allows electric current to travel through a shorter loop than it should

• A circuit that has no resistance

• A circuit that is open and incomplete

What can a damaged electric cord cause?

• A decrease in electric current

• A severe shock if it allows current to pass from the cord to a person

• An increase in electric resistance

• A complete stop of electric current

What is one of the dangers of electricity mentioned in the lesson?

• It can cause water to boil

• It can cause severe burns and even death

• It can make appliances work faster

• It can reduce energy consumption

What is a common cause of electric hazards and fires?

• Overuse of electric appliances

• Short circuit

• Using too many extension cords

• Low voltage

What does an electric cord contain?

• One wire that carries current to the appliance

• Two wires: one that carries current from the outlet to the appliance and one that carries current back

• Three wires: one for power, one for ground, and one for data

• A single wire that loops back to the outlet

What can happen if a person touches a damaged electric cord?

• They will feel a slight tingling sensation

• They can receive a severe shock

• They will be unaffected

• They will be insulated from the current

Why is a short circuit dangerous?

• It increases the efficiency of the circuit

• It can cause electric current to bypass safety mechanisms

• It reduces the voltage in the circuit

• It makes the circuit more stable

What is one of the potential outcomes of a short circuit?

• Improved energy efficiency

• Serious fires

• Reduced electric bills

• Enhanced appliance performance
