Safety and work practicesQuestion 282 of 1506

Why can a bird rest safely on a high-voltage line?

Its feathers insulate it completely from the line
The line voltage is too low to matter to it
Its feet are very poor conductors of any current
It touches one point only, so no voltage is across it

Show answer

Correct answer: It touches one point only, so no voltage is across it

Voltage exists between two points. Both feet touch the same wire, so no voltage drives current through the bird.
