How Can Birds Perch on Electric Wires Without Getting Shocked?
How Can Birds Perch on Electric Wires Without Getting Shocked? Birds don’t get shocked when they sit on electrical wires because they are not good conductors of electricity. Their cells and tissues do not offer electrons an easier route than the copperwire they’re already traveling along. As a result, the electricitybypasses the birdsand keeps flowing along the wire instead.
A bird doesn’t receive a shock when it lands on an electric wire because it lands on only one wire. Electricity takes the path of the least resistance — it flows through some materials much more easily than others. It is simply easier for the electricity to continue along the metal wire than it is for it to detour through the bird.
If the bird landed on two wires with different voltages, however, the electricity would flow through the bird from the wire with the higher voltageto the wire with the lower voltage, and the bird would be electrocuted.
This is because its body would become a path for the electricity to reach with a different voltage. This is why power lines hang high in the air with plenty of space between the wires! So now we have the answer to the question. How Can Birds Perch on Electric Wires Without Getting Shocked?
Do birds get any warmth from perching on high wires? Only high tension wires that are transferring kilo volts to mega volts give off any appreciable heat. Some birds will land on these wires in systems that run voltages in the lower kilo volt range and probably do so to gain the heat from the wires on a cold day.
