Question

A bird perches on a bare high power line, and nothing happens to the bird. A man standing on the ground touches the same line and gets a fatal shock. Why?

Answer 1

Hint:On one side, the voltage has a high potential, while the other is grounded. Now, if you stand on the ground and hold the main high-potential line, you are in parallel with the voltage source. As a result, the same potential goes through you and you are shocked.

Complete answer:
Only if there is a potential difference will current be allowed to flow. Birds have the ability to make their body's potential equal to the wire's potential, resulting in a total potential difference of zero and no current flow. However, when a man touches a live wire, a potential difference is generated, and electrons are given a path to go through the person's body.

When a man stands barefoot on the ground and touches the same line, the electrical circuit is completed through the earth. Man's hands have a lot of potential, but his feet have a low potential. As a result, a tremendous amount of electricity passes through the man's body, causing a deadly shock.It's important to note that you can only feel the current if it completely flows through your body.

However, because rubber is a poor conductor of electricity, it prevents electricity from passing from your body to the earth when you wear rubber slippers. That is why you are unaffected by the shock. When birds sit on electric wires, they are not in contact with anything else, so the current that enters their bodies from the cable has nowhere to go.

Note:You may think of the air as their rubber slippers in this situation. Because air is a poor conductor of electricity, current cannot flow through it. An open circuit with air is referred to as an open ended circuit, and current does not flow in an open ended circuit.
