Power Factor Correction is a technique which uses capacitors to reduce the reactive power component of an AC circuit in order to improve its eficiency and reduce current. When dealing with direct current (DC) circuits, the power dissipated by the connected load is simply calculated as the...

Nowadays it is very easy to display numbers and letters across multiple LED displays using micro-controllers, such as the Arduino or Raspberry-Pi, along with a small bit of software related code to display the required digits. But sometimes as an Electronics student or hobbyist we want to...

An FET constant current source is a type of active circuit which uses a Field Effect Transistor to supply a constant amount of current to a circuit. But why would you want a constant current? Constant current sources and current sinks, (a current sink is the reverse of a current source) are a...

Electrical Energy is the ability of an electrical circuit to produce work by creating an action. This action can take many forms, such as thermal, electromagnetic, mechanical, electrical, etc. Electrical energy can be both created from batteries, generators, dynamos, and photovoltaics, etc. or...
