Show WHAT IS electricity some ot the various theories on the current Cur reut well what is it it is scarcely possible to say there are many of them it is evidently something of which we cannot take a part we cannot cut a piece of it off and subject it i to analysis nor can we pour a little of it into a bottle for future study and contemplation it is like the wind its effects can be measured its force strength and quantity can now be calculated to a very nice degree still to liken it to the wind it is a stupendous power a mighty typhoon blowing as it were without moving two ways at ance along all parts of its path giving off a lialo of magnetism at right angles to that everywhere one of the nicest theories perhaps is the one that considers electricity a condition of atoms brought about by chemical action as in a battery cell or by what might be called a severe irritation of the magnetic halo as in a dynamo and by other means such as heat and friction what this condition is is beyond us it may be a violent rotation or it may be an equally violent vibration of atoms probably the arc light would prove it to be a vibration but as no man nas seen an atom ai any time not even with the most powerful microscope it is impossible to say friction in some form or other is present as heat is produced before burning or destruction st takes place |
