Electricity/Electricity and matter

Electricity conductor
Electricity conductor refers to matter that conducts electricity. Depend on the capability to conduct electricity, matters are divided into 3 types


 * Conductor . Material that conducts electricity easily include all Metal like Copper (Cu), Iron (Fe)...
 * Semi-conductor . Material that conducts electricity somewhere between conductor and non-conductor include all Semi-metal like Silicon (Si), Germanium (Ge)...
 * Non-conductor . Material that does not conduct electricity at all . For example Rubber

Application
All conductors are used to make passive electric components like
 * Resistor
 * Capacitor
 * Inductor

All semi-conductors are used to make active electric components like
 * Diode
 * Transistor
 * FET
