Electronic Components (Leaving Cert Engineering): Flashcards

Two conductive plates separated by dielectric material

Insulating material between the conductive plates

Blocks DC current, allows AC to pass through

Component that restricts flow of electric current

$I \propto V$, $I \propto 1/R$

Semiconductor allowing current in one direction only

N-type (excess electrons) + P-type (deficiency)

Converts AC to DC by one-direction current flow

Semiconductor that amplifies or switches signals

Emitter, base, and collector

Small base current controls large collector current

Stores energy in magnetic field when current flows

Electromagnetic induction from changing current

Electromagnetic switch controlled by electromagnet

Separates low voltage control from high voltage power
