Machine that converts electrical energy into mechanical energy
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
Semiconductor device used to amplify & switch electronic signals & power/at least 3 terminals for connection to circuit/developed in Brattain, Shockley, & Bardeen in 1947
Property of material that varies with change in temperature that measures its ability to conduct electric current/reciprocal of resistivity
Flow of electric charge that periodically reverses direction/Tesla favored this form in War of Currents
Early form of capacitor consisting of a glass jar with layers of metal foil on the outside and inside/invented by von Kleist & Musschenbroek (1745)/named for Dutch city
Used in levitation demos/zero resistance & expulsion of B-field/discovered by Onnes/characterized by Meissner effect/usually at very low temps/some ceramic materials at much higher
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
Transfers energy between 2 or more circuits by electromagnetic induction/used to increase or decrease voltage of an alternating current
Passive two-terminal electrical component that reduces current flow and voltage within a circuit/converts electrical energy to heat
One or more electrochemical cells that convert stored chemical energy into electrical energy
Device that converts mechanical energy into electrical energy for use in an external circuit
Passive two-terminal electrical component which resists changes in electric current passing through it/formed from coiled wire/stores & releases energy by induction
Insulating material placed between the plates of a capacitor to increase its capacitance
Property of material that varies with change in temperature that measures how strongly it opposes flow of electric current/reciprocal of conductivity
Minimum voltage that causes a portion of an insulator to become electrically conductive/for diodes it's the min voltage to make it conduct in reverse
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
Originally know as a condenser/2-terminal component used to store electrical energy/have 2 plates w/dielectric (insulator) in between
Coined by Ampere/coil of wire wrapped into a tightly packed helix/produces a uniform magnetic field when an electric current is passed through it/used as eletromagnet or inductor
Transformer where primary winding has more turns than secondary winding
Foundational to electronics/conductivity inc's w/inc temp/quantum physics explains movement of electrons & holes inside lattice/enhanced by 'doping'/used in transistors/Si,Ga,Ge
Circuit type with a voltage source, resistors, & capacitors
States that current through conductor between two points is directly proportional to potential difference across two points/ Current equals potential difference over resistanance
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
Transformer where primary winding has fewer turns than secondary winding
Flow of electric charge produced by batteries, thermocouples, solar cells, and dynamo-type machines that is unidirectional/favored by Edison in War of Currents
Usually a bluish glow near pointed conductors w/high voltage/electrical discharge by ionizing fluid surrounding a conductor/less than breakdown voltage
