Questions & Step-by-Step Solutions

What is the primary function of a transmission line's insulator?
  • Step 1: Understand that a transmission line carries electricity over long distances.
  • Step 2: Know that insulators are materials that do not conduct electricity.
  • Step 3: Realize that insulators are placed on transmission lines to hold them up.
  • Step 4: Learn that insulators prevent electricity from escaping the line and going into the ground.
  • Step 5: Conclude that the primary function of an insulator is to support the line and keep the electricity contained.
