Alternating Current (AC) It's common sense electrons can flow either forwards or backwards along a conductor. We learnt with DC that DC is when current flows only in one direction. Alternating curren

Direct Current (DC) Current can flow forwards or backwards through a conductor. When it only flows in one direction it is know as direct current (DC). When if flows in both directions it is know as A

Drawing Circuits When designing circuits it is not practical to draw physical likenesses of the components you wish to use. In place of each component a symbol is use to represent it. For example:

Thyristors Thyristors have a similar function to Unijunctions they act as switches. Thyrstors use current flow as a switch. There are two types of thyristors. Silicon-Controlled Rectifi

Types of Diodes Small Signal Diode - Low voltage/current diodes. Power Rectifier - High voltage/current diode. Bridge rectifiers are are four diodes pre-installed into one component, useful for
