Electrical Safety & Basics Quiz

The word electrocution refers specifically to which situation?

• Injury from touching a live wire

• Feeling a mild zap from static

• Death caused by electric shock

• A small electrical burn on the skin

If electricity passes through your body but you survive, it is called:

• Electric spark

• Electrocution

• Electric shock

• Current transfer

Why is the human body so sensitive to electrical currents?

• Our nervous system depends on tiny electrical signals

• Our hair can store static charges

• Bones conduct voltage

• We are 100% water

About how much current can start interfering with a person’s breathing?

• 200 milliamps

• 5 milliamps

• 20 milliamps

• 15 milliamps

Which two things decide how much current will move through a person’s body?

• Voltage and body resistance

• Pressure and temperature

• Wire size and power source age

• Frequency and battery charge

Which condition makes a person more vulnerable to electric injury?

• Wearing thick gloves

• Using battery-powered devices

• Damp or broken skin

• Standing on a carpet

What is the role of a defibrillator during a cardiac emergency?

• To restart or regulate heart rhythm using an electric shock

• To slow a dangerously fast heartbeat

• To improve blood flow using air pressure

• To magnetically keep the heart contracting

Saying electricity “takes the easiest path to ground” means:

• It always travels in a straight line

• It follows the route with the least resistance

• It prefers the safest possible material

• It flows equally in all directions

If your body becomes part of the path to ground, the danger is:

• You could be seriously injured or killed

• The power supply could drain faster

• Electronics may shut down

• Current flow would slow

Which two particles are located in the nucleus of an atom?

• Protons and neutrons

• Protons and electrons

• Neutrons and electrons

• Ions and electrons
