The video explains why birds can safely perch on power lines without getting electrocuted. It discusses the movement of electric currents and how circuits work, highlighting that birds avoid forming a circuit by not touching two wires with different potentials. Larger birds, however, are at risk of electrocution when they accidentally complete a circuit. The video also mentions efforts by utility companies to design safer power poles. Finally, it promotes Skillshare classes related to electricity and other topics.
