Transistors

A Transistor (the construction of Transfer Resister) is an electric semiconductors (called electrode).  These are referred to as active component in contrast to “passive component” such as resistance or capacitors which ably have two electrodes (referred to as being “bipolor”).

A MOS (Metal Oxide Semiconductor) transistors is the most common type pof transistor used to designed integrated circuits MOS transistors have two negative charged area, respectively called sourced (which has almost zero charge) and drain (which has a 5v charge) separate by a positively charged region, called a substrate).  The substrate has a control electrode overlaid, called a gate that allows a charge to be applied to the substrate.
