Why the Capacitor in Your Power Supply Filter is Too Big

Why the Capacitor in Your Power Supply Filter is Too Big

The job of the capacitor in the output filter of a DC power supply is to maintain a constant DC value by removing as much power ripple as possible. Because these capacitors have a DC value, they are actually storing a lot of energy that never gets used.


AC-DC Converters - Disassembling a Linear Power Supply

AC-DC Converters - Disassembling a Linear Power Supply

An AC-DC wall adaptor gets disassembled to see what components are used to build it, then the purpose of each component is analyzed.


The Twelve Cardinal Rules of Fuseology

The Twelve Cardinal Rules of Fuseology

As designs become smaller, faster and more complex, so do circuit protection decisions. Learn more about circuit protection with this guide.


Design a Luxmeter Using a Light Dependent Resistor

Design a Luxmeter Using a Light Dependent Resistor

Understanding Electricity with Hydraulics

Understanding Electricity with Hydraulics

An overview of how the concepts of electron flow and the role of individual circuit components can be related to the flow of fluid in pipe networks. The analogy between hydraulics and electricity is a useful tool for teaching and for those who are struggling to understand how circuits work.


What is a Transmission Line?

What is a Transmission Line?

Explanation of what a transmission line is, and the conditions under which it exists. Uses lumped element model to derive differential equations and manipulates the equations to get telegraph equations. Uses solutions to telegraph equations to get characteristic impedance and propagation constant and looks at matched and unmatched load cases.
