Study Sheets Answer Key

Episode 1 – Electricity Basics

  1. b) transmission lines.
  2. A substation reduces the strength of high-voltage electricity.
  3. b) a circuit.
  4. d) ground.
  5. If you touch a circuit in which electricity is flowing, electricity will travel through you to the ground and give you a serious or fatal shock.

Episode 2 – Conductors & Insulators

  1. Bare electrical wires are dangerous because there is no insulating material protecting you from the electricity in the circuit. If you touch a bare wire, you could be shocked.
  2. a) the plastic-like coating on power cords.
  3. c) water.
  4. The human body is a good conductor of electricity because the body is more than 60% water and water is an excellent conductor.
  5. If you overload an outlet with too many plugs it could cause a fire.

Episode 3 – Outdoor Electrical Safety

  1. It is unsafe to touch the string of a kite that is caught on a power line because the electricity in the line could use the string, the kite, and you as its path to the ground, and you could get shocked.
  2. Before climbing any tree, look all around the tree to make sure there are no power lines running near it.
  3. It is unsafe to climb into a substation because contacting the equipment inside could shock or kill you.
  4. a) 3 metres.

Episode 4 – Indoor Electrical Safety

  1. True.
  2. Removing stuck toast from a plugged-in toaster with a metal fork is dangerous because the fork could act as a conductor for the electricity in the toaster, and you could be shocked.
  3. Balancing a plugged-in blow dryer on the edge of a full bathtub is dangerous because if the dryer falls in, it will energize the water and create a major shock hazard.
  4. A power cord that is under a rug could get stepped on a lot. This would damage the cord insulation and cause a shock or fire hazard.
  5. c) removing stuck toast from an unplugged toaster.

Episode 5 – Fallen Power Lines

  1. b) utility workers.
  2. The safest way to exit a car with a power line on it is to jump as far away from the car and the power line as you can. Do not touch the car and the ground at the same time. Land with your feet together and shuffle at least 18 metres away.
  3. d) If your feet remain together your legs cannot form a circuit with the electricity in the ground.
  4. False.
  5. b) touch it.
