      Electric Field

    1. Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object.


    1. Electric potential energy is the energy that is needed to move a charge against an electric field. You need more energy to move a charge further in the electric field, but also more energy to move it through a stronger electric field.


    1. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. Sunlight travels through the vacuum to reach the Earth, which is an example of an electromagnetic wave. These waves are called electromagnetic waves because they form when an electric field that interacts with a magnetic field.


    1. Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a conducting material will permit charge to be transferred across the entire surface of the object.

      What are conductors?

    1. Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

      This is by far the best explanation I found.

    1. “Electricity;”

      Like the air-pump, recent experiments with electricity also fascinate Victor even while he reaches for a non-modern "system" that would be antithetical to empirical scientific reason. See Iwan Morus, Frankenstein's Children: Electricity, Exhibition, and Experiment in Early Nineteenth Century London (Princeton UP, 1998).

    2. I saw the dull yellow eye of the creature open; it breathed 098hard, and a convulsive motion agitated its limbs

      This description recalls an experiment by Giovanni Aldini, a Professor of Experimental Philosophy at the University of Bologna, Italy. He was also Luigi Galvani’s nephew and a strong proponent of the latter’s work. In early 1803, Aldini conducted an electrical experiment on the corpse of Thomas Foster at Newgate Prison in London. A voltaic pile sent electric currents through the dead man’s body, causing it to contract and contort and one eye to open. Such experiments were well known to the Shelleys, who attended physiological lectures in London between 1802 and 1816.

    1. Before this I was not unacquainted with the more obvious laws of electricity. On this occasion a man of great research in natural philosophy was with us, and, excited by this catastrophe, he entered on the explanation of a theory which he had formed on the subject of electricity and galvanism, which was at once new and astonishing to me. All that he said threw greatly into the shade Cornelius Agrippa, Albertus Magnus, and Paracelsus, the lords of my imagination; but by some fatality the overthrow of these men disinclined me to pursue my accustomed studies. It seemed to me as if nothing would or could ever be known. All that had so long engaged my attention suddenly grew despicable. By one of those caprices of the mind, which we are perhaps most subject to in early youth, I at once gave up my former occupations; set down natural history and all its progeny as a deformed and abortive creation; and entertained the greatest disdain for a would-be science, which could never even step within the threshold of real knowledge. In this mood of mind I betook myself to the mathematics, and the branches of study appertaining to that science, as being built upon secure foundations, and so worthy of my consideration. Thus strangely are our souls constructed, and by such slight ligaments are we bound to prosperity or ruin. When I look back, it seems to me as if this almost miraculous change of inclination and will was the immediate suggestion of the guardian angel of my life— the last effort made by the spirit of preservation to avert the storm that was even then hanging in the stars, and ready to envelope me. Her victory was announced by an unusual tranquillity and gladness of soul, which followed the relinquishing of my ancient and latterly tormenting studies. It was thus that I was to be taught to associate evil with their prosecution, happiness with their disregard. 29It was a strong effort of the spirit of good; but it was ineffectual. Destiny was too potent, and her immutable laws had decreed my utter and terrible destruction.

      In this section, in 1831 three paragraphs of text replace a five-paragraph section in 1818.

      Awed by the destructive power of the lightning-blast and their companions discourse on galvanism, Victor throws aside the "tormenting studies" of both medieval alchemy and natural philosophy which had hitherto fueled his sense of wonder and formed the basis of his intellectual obsessions. Turning instead to mathematics, he enjoys a brief respite from his torments, but his former desires will overtake him again.

    1. Control rods are usually used in control rod assemblies (typically 20 rods for a commercial PWR assembly) and inserted into guide tubes within a fuel element. A control rod is removed from or inserted into the central core of a nuclear reactor in order to increase or decrease the neutron flux, which describes the number of neutrons that split further uranium atoms. This in turn affects the thermal power, the amount of steam produced and hence the electricity generated.

    1. the language of electricity — stimulant, reactor, and voltage

      That makes me think of J.D. Peters, Speaking Into the Air and Jeffrey Sconce, Haunted Media
