"To him that rideth upon the heavens of heavens, which were of old; lo, he doth send out his voice, and that a mighty voice."—Psalm lxviii.
601. Why does electricity seize upon bell wires and iron fastenings?
Because copper wires are the very best conductors of electricity; and iron articles are also good conductors.
602. Supposing electricity to attack a bell wire, where would the point of danger exist?
At the extremities of the wire, where the conducting power of the wire would cease, and the electricity would seek to find another conductor.
603. Are umbrellas, with steel frames, dangerous in an electric storm?
They are dangerous in some degree, because they might convey electricity to the hand, and then transfer it to the body. But, generally speaking, when it rains, the rain itself, being a good conductor, relieves the disturbance of electricity by conveying it to the ground.
