How birds can sit on power lines safely?

Expert Solution & Answer

Answer to Problem 1Q

Solution:

Birds are not a poor conductor of electricity, so they offer good resistance, that’s why they can sit on the power lines safely.

Explanation of Solution

Electric current follows the path of least resistance, when the birds sit on the power lines they do not get an electric shock because they are a poor conductor of electricity and gives high resistance to the flow of current compared to the copper wire in which current already flows, that’s why current does not flow through the bird and they can safely sit on the power lines.

While when you lean a metal ladder up against a power line, then actually you are making a short circuit, as the voltage of the ground is very low compared to the power line, and due to higher potential difference, the current flows through the ladder and you feel the shock.
