Chapter 35, Problem 27A

Why are the wingspans of birds a consideration in determining the spacing between parallel wires in a power line?

To determine

The reason for considering the wingspan of the birds for the spacing between the parallel wires in the power line.

Explanation of Solution

Introduction:

If the parallel wire in the power line comes in contact with each other then potential difference across the parallel wire becomes the same and it causes the short circuit of the parallel wires.

If the spacing between the parallel wires in a power line is less than the wingspan of the birds, then a short circuit of the parallel line occurs due to the touch of both parallel wires. This may cause an interruption in the power supply.

Conclusion:

The wingspan of the birds is considered for spacing between the parallel wires in the power line to avoid the interruption in the power supply due to the short circuit between parallel wires.
