Why can a bird sit on overhead Power lines and not get electrocuted?

Birds can sit safely on a Power line because they do not complete a circuit with the ground. The ground acts like one of the wires in a circuit and so do you, this is called being 'earthed'.

Theme

Birds can touch Power lines because they are not 'earthed'. You cannot touch them as you are earthed.

Aim

  1. Understand the concept of 'earth'
  2. Understand the danger it causes
