Let a conductor, say a metallic sphere, be supported by a metal rod of negligible electric capacity whose other end is earthed.
Displaced by the sphere, and assumes a statical state of conditions and that the conductor itself exerts no disturbing influence.
Linss (6) found that an insulated conductor charged either positively or negatively lost its charge in the free atmosphere; the potential V after time t being connected with its initial value Vo by a formula of the type V = Voe - at where a is constant.
Faraday's term " electrode," literally " a way (650s) for electricity to travel along," might be well applied to designate the insulated conductor along which the electric messenger is despatched.
Theoretically for a given outside diameter of core the greatest speed of signalling through a cable is obtained when the diameter of the conductor is 606 (1/,/e) the diameter of the core, but this ratio makes the thickness of the guttapercha covering insufficient for mechanical strength.
United States, made a very elaborate investigation of the propagation of electric currents through the earth, either soil or water (see " The Earth as a Conductor of Electricity," Amer.
This elevated conductor is now called the antenna, aerial wire, or air wire.
In later wells the conductor has been replaced with an 8-in.
This mode of suspension enables the conductor CC to vibrate freely like a balance, but at the same time very large currents can easily be passed through this perfectly flexible joint.
A symphony was produced at the Gewandhaus concerts in 1833, and in the following year he was appointed conductor of the opera at Magdeburg.
The action was started in the cold, the alkali being slightly moistened to render it a conductor; then, as the current passed, heat was produced and the alkali fused, the metal being deposited in the liquid condition.
The crucible was surrounded with a bad conductor of heat to minimize loss by radiation.
Depending on the fact that the electrical conductivity of a metallic conductor is decreased by heat, it consists of two strips of platinum, arranged to form the two arms of a Wheatstone bridge; one strip being exposed to a source of radiation from which the other is shielded, the heat causes a change in the resistance of one arm, the balance of the bridge is destroyed, and a deflection is marked on the galvanometer.
Anubis came to be considered especially the attendant of the gods and conductor of the dead, and hence was commonly identified with Hermes (cf.
This experiment proves that when a charged body acts by induction on an insulated conductor it causes an electrical separation to take place; electricity of opposite sign is drawn to the side nearest the inducing body, and that of like sign is repelled to the remote side, and these quantities are equal in amount.
This provides us with a definition of a unit of electric force, for it is the strength of an electric field at that point where a small conductor carrying a unit charge is acted upon by unit mechanical force, assuming the dielectric constant of the surrounding medium to be unity.
As it came to a stop the conductor called out in a loud voice.
The conductor helped her off the car and then the engineer started his train again, so that it puffed and groaned and moved slowly away up the track.
The conductor said it was the worst quake he ever knew.
The conductor, too, was kind.
