CURRENT EL

Apuntes

CURRENT ELECTRICITY Refers to charges in movement within a conductor. Allows electrons to freely move. EX: METALS ELECTRIC CIRCUITS Paths made of conductive material through which electrons flow in an ordered manner. -> ELECTRIC CURRENT CURRENT = # OF ELECTRONS -————————— TIME COULOMBS C = ——————— = —— -> Ampère (A) SECONDS S VOLTAGE = JOULE = J -———— —— -> Volt (V) COULOMB C RESISTOR Consumes some of the energy and turns it into heat (JOULE EFFECT) They display a certain resistance.
