In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...

A new type of circuit board which is almost entirely biodegradable could help reduce the environmental harms of electronic waste, its inventors say. Researchers from the University of Glasgow have ...

Abstract: We analyzed ac electrical measurements of a ferromagnetic inductor as a dynamical nonlinear circuit element and observed a pinched hysteresis loop in the plot of the time derivative of its ...

Get ready to dive into AC circuits! ⚡🔌 In this video, we’ll walk through how to calculate current and power in an AC circuit with a resistor. Perfect for understanding electrical concepts in action! ...

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...

While capacitance is the primary characteristic of capacitors, the concept of “capacitor resistance” is essential for understanding their real-world performance. Capacitors are fundamental components ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

It's essential to understand how power and energy calculations relate, especially with the increased importance of energy efficiency. Calculations of power and energy are relatively straightforward ...
