How fast does electric current travel through the wires?
There seems to be a speed limit in the universe, and nothing we know of can out distance this limit. It is not quite accurate to say that the fastest traveler is light, for many other things can equal its speed. One is a current of electricity sent speeding through a wire circuit by a man made generator. The objects needed to make an electric current are as simple as abc. There must be a magnet of the right shape, a wheel or bar made of copper and a long length of copper wire all in one piece. A magnet, of course, surrounds itself with an invisible magnetic field of force lines. The magnet used to make the first dynamo or generator was shaped like a horseshoe. At the open end of the u shape, the force lines interlock with extra strength. The magnet was fixed flat on a board. A copper disc was then fixed so that it could be turned like a wheel between the open end of the horseshoe. The two ends of the copper wire were attached to the little dynamo. When the wheel was turned by a hand cr
