InfoAnswer
Passive two-terminal electrical component which resists changes in electric current passing through it/formed from coiled wire/stores & releases energy by induction
Instrument that combines several measurement functions in one unit/normally measures voltage, current, & resistance
2-terminal elect. component w/asymmetric conductance/low resistance in 1 direction, high in other/semiconductor & vacuum tube forms/converts AC to DC by rectification
Instrument used to measure unknown electrical resistors below 1 ohm/called a Thomson Bridge in some countries
Branching electric discharges that sometimes appear on surface or in interior of insulating materials/due to high voltage/often burned into skin of people struck by lightning
Device that converts a signal in one form of energy to another form of energy
Region in space where every point has the same potential/can be lines or surfaces/lines look like a topographical map/always perpendicular to E-field lines
Building block of analog circuits/voltage amplifier w/3 terminals used in signal conditioning, filtering or to perform mathematical operations (+, -, integration, differentiation)n
2-terminal resistor w/sliding or rotating contact (wiper) that forms an adjustable voltage divider/most common way to vary resistance in circuit/coined by Wheatstone in 1845
Named for Erasmus of Formia/weather phenomenon where coronal discharge is created on pointed object in an E-field in the atmosphere/seen on masts of wooden ships in thunderstorms
Usually a bluish glow near pointed conductors w/high voltage/electrical discharge by ionizing fluid surrounding a conductor/less than breakdown voltage
Also known as quadratic mean/method used to calculate effective value of AC current that delivers same power as DC current & eff. AC voltage = peak voltage div by sqrt(2)

Flow of electric charge produced by batteries, thermocouples, solar cells, and dynamo-type machines that is unidirectional/favored by Edison in War of Currents
Enclosure formed by conductive material or mesh of such material that blocks external E-fields and doesn't allow current to flow inside/a car struck by lightning is an example
Effective resistance of an electric circuit or component to alternating current/complex ratio of voltage to current in AC/has both magnitude & phase
Effect where charge builds up on a object because of friction (Ex. amber rubbed with wool/glass rubbed w/silk/rubber rubbed w/fur)
Instrument that measures electrical resistance/form circuit w/in themselves/don't hook into existing circuit/sends constant I thru resistance, measures V to calculate R
Circuit type composed of capacitors and inductors/energy oscillates from capacitor to inductor and back
Wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters
Materials that should conduct electricity under conventional band theories but are insulators when measured (particularly at low temperatures) due to electron-electron interactions
Law of physics that calculates the force between two charged particles
One or more electrochemical cells that convert stored chemical energy into electrical energy
Production of voltage difference across a conductor, transverse to electric current in conductor & magnetic field perpendicular to the current
Device that converts mechanical energy into electrical energy for use in an external circuit

Electric charge that accumulates in certain solid materials in response to applied mechanical stress/discovered in 1880 by Jacques & Pierre Curie/used in guitar pickups & lighters
Insulating material placed between the plates of a capacitor to increase its capacitance
Amount of electric pot. energy a point charge would have if located at a given point in space/equal to work done by E-field to move 1 unit of positive charge from infinity to point
Expulsion of magnetic field from superconductor during transition to superconducting state/happens when cooled/important paradigm for Higgs mechanism
