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

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

Transformers Transformers are one of the major uses of coils. They are made of two or more separate coils of wire wrapped around a common core, normally made of laminated iron sheets. Like so...
