  • Negative electricity

    An electric charge caused by an excess of negatively charged electrons.  

  • Magnetic electricity

    Electricity induced by a magnetic device.  

  • Induced electricity

    Electricity generated in a body from another body nearby without contact between them.  

  • Galvanic electricity

    Electricity generated by chemical action.  

  • Frictional electricity

    Static electricity generated by rubbing two objects together.  

  • Electricity

    A form of energy that is generated by the interactions of positive and negative charges and that exhibits magnetic, chemical, mechanical, and thermal effects. The movement of particles around an atom that creates pure energy.  

  • Electric field

    A electric field that may surround an object placed in a rapidly changing magnetic environment, such as one generated by a magnetic resonance imaging device. The region of electrical sensitivity surrounding a charged conductor or charged object.  

  • Electrical stimulation

    Use of electric current to affect a tissue, such as nerve, muscle, or bone. In the latter case, the stimulation is used to facilitate and hasten healing of fractures.  

  • Electrical source imaging

    A means of mapping the electrical activity of organs such as the brain or heart in order to diagnose or treat diseases such as seizures or dysrhythmias. ESI relies on the collection via external sensors of the electrical activity generated by multiple tissue sites within an organ, and the mathematical manipulation of that data to…

  • Electrical patch

    An electrical device for delivering medications transdermally. The slight electric current used in electrical patches allows larger molecules to be transported through the skin. This technique differs from electrophoresis by the electrical current used, which increases the permeability of the skin.
