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...

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

Unijunction Transistor The unijunction transistor (UJT) works like a switch. It doesn't amplify the voltage, it just lets current through or not depending on the in input voltage. Irrespective

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

Resistors Resistors limit or reduce the current passed across them. They do this by by having different densities of different materials within them, the most common of which is carbon. Make
