Safety Quiz Part 1 - Electricity

What does the word electrocution originally mean?

• A strong electric shock

• Death by electric shock

• Lightning strike

• Visible electric burns

What do we typically call a non-fatal experience of electricity passing through the body?

• Zap

• Electrocution

• Electric shock

• Overcharge

Why are our bodies especially responsive to electric currents?

• Bones conduct electricity

• Our blood has metal in it

• Our nervous systems use electric signals

• We generate static electricity naturally

What is the minimum amount of current that can cause someone to stop breathing?

• 5 milliamps

• 20 milliamps

• 50 milliamps

• 100 milliamps

Why is touching a phone charger’s live wire typically not deadly?

• It has low voltage

• The current is turned off at night

• The body absorbs all the electricity

• Very little current actually enters your body

What are the two main factors that determine how much current enters your body?

• Amperes and sparks

• Voltage and resistance

• Heat and muscle tension

• Pulse rate and nerve signals

In the video’s analogy, if current is water and voltage is water pressure, what does resistance represent?

• A pump

• The water tank

• The narrowest part of the pipe

• The direction of flow

Which of the following increases your risk of a harmful electric shock?

• Wearing rubber shoes

• Dry, intact skin

• Wet or damaged skin

• Low resistance in your charger

What voltage is considered “high voltage” and dangerous enough to break through the skin’s resistance?

• 120 volts

• 230 volts

• 300 volts

• 500 volts

How can a defibrillator help in some cases of heart malfunction?

• It strengthens the pulse

• It reduces blood pressure

• It gives a brief shock to reset heart rhythm

• It numbs the nerves to reduce pain
