Question

A bird sitting on a power cable does not feel any shock because of

Answer 1

Hint: You'll have noticed that animals and birds do not follow the rules of electricity. The body type of a bird or an animal is different from the humans. Human beings are conductors because we have electrical impulses running through the nervous system. Here, we need to think about whether birds are conductors or insulators.

Complete answer:
There are two reasons why a bird sitting on a power cable does not feel any shock.
The answer to the present question has got to do with how electricity flows. It'll always move along the trail of least effort and flows best through conductors. The electrical wires are made up of copper and are great conductors. Birds aren't good conductors. That’s one reason they don’t get shocked once they sit on electrical wires. The energy does not flow through the bird's body and keeps flowing along the wire instead.
The second reason that birds do not get a shock while sitting bare on a power cable is;. There’s no voltage difference when we talk about a single wire. For electrons to move, there must be a difference in electrical potential.
Electric Potential Difference: The work done in moving a unit positive charge from one place to another is called electric potential difference within an influence of electric field. It is denoted by V.
For instance, energy flows from areas of high voltage to areas of low voltage. If it flows through one power cable at 35,000 volts, it’ll continue along to move towards the path with less hindrance. So, the birds will not get a shock. Birds can sit on a power and not get electric shocks because the electricity flowing through wires wants to actually get to the ground.
So, these are the two major and important reasons for the fact that a bird sitting on a power cable does not feel any shock. Electric current flows better on a path which has less resistance.

Note:
The birds are not touching the ground or they are holding something that makes a contact with the ground. So, the electricity will stay in the wires it is flowing through. But if a bird with large wings touches two wires simultaneously or power pole at the same time, it gives electricity a path to the ground, and could be shocked.
