Electric Quantity And Tension

.hrectric quantity and tensión - or 111nsity - are tenns based on the assumpion that electricity is a fluid. Quanity is the amount of the fluid that a body contains as its charge and the tenion or intensity on any pointof its sur'ace - insulated electricity lies on the urface - is the depth, or if the depth remain the same the density of the fluid at that point. The qnantity has refernce to the number of partióles electriied and the amount of force lodged in ach; the tensión has reference simply ;o the indnctive force lodged in each. -"articles that are highly electrified nust polarize powerfully the particlés near them, and if powerful enough anse discharge. Tensión or intensity, herefore, is the power to polarize and ffect discharge. The quantity of elecricity passing in á curren t is estimated )y the power of the current to deflect he rnagnetic needie by the cheinical deomposition it efïects, or by the temperture to which it raises a wire of given fchickness and material. The tensión or intensity of the current is the power which it has to transmit a current against resistance, such as that oft'ered by a bad, long or thin conductor. Teniion. strictly speaking, is not a property of the current. butof the batterv which
