Show to alia speed 0 electricity philadelphia scientists tista are preparing to find out how fast an electric carrent travels an experiment will bo made probably from the franklin institute by connections over the atlantic cable to liverpool and return A recent test appeared to show that an electric current is a slow coach aa compared to light being only able to get over to europe and bade in something like a second or at the rate of only some miles a minute while light ambles along at a million miles a minute gait the philadelphia scientists who are proposing to make further investigations are not satisfied to give up th record to sunlight and hope to prove that the electrical current if not handicapped is the swifter element the most recent experiment was tried at mcgill college montreal the current was transmitted in montreal was transferred to the cable at the newfoundland found land cable station by means of thompsons Thomp sons mirror galvanometer sent across to the station at liverpool and returned to montreal by the same method the distance traversed partly by overhead wire and partly by cable was miles from the time the current left the key in montreal until it returned 10 the receiver in tha earne office just one second and one twentieth of a second had elapsed and the conditions were not as good as they might havo been hence the further experiment to be made her the rapidity with which the current travels over short wires with no delay indicated unlimited possibilities in the direction of practical tests professor marks of the edison electric ligh company is authority for the assertion that if tho globe was encircled with a continuous cable a current would travel the entire distance in a trifle over three seconds at this rate a current would travel to the sun covering the distance of miles in three and a half i minutes or twice as fast as light phila i delphia record |
