Electronics - unit 4.4 Flashcards
alternator
An electric generator used for producing alternating current.
analog
Of, relating to, or being a mechanism in which data is represented by continuously variable physical quantities.
current
The total amount of electrons flowing through a circuit per unit time; measured in Amperes (one coulomb of electrons passing a single point per second).
digital
An information system whose signals have only two states, 1 (closed) or 0 (open).
generator
A device that converts mechanical energy to electrical energy.
load
A force applied to an object (e.g. “a 30 lb load” or a load on an electrical system, like a motor, light, or speaker.)
magnetism
A force that exists around magnets that attracts ferrous materials and is used in motors and generators
motor
A device used to convert electrical energy to mechanical energy.
Ohm’s law
The relationship of voltage, current and resistance in a circuit I=V/R, V=IR, R=V/I
parallel
Multiple pathways in a circuit.
power
Force over time. Measured in Ft Lbs Newton Meters or Watts.
rectification
The process of converting AC into DC.
relay
Electromechanical switch where contacts are opened or closed by a control circuit in order to switch a secondary circuit
semiconductor
Materials whose electrical conductivity can be precisely altered by appropriate manufacturing processes.
series
A circuit with only one pathway for electrons.
