Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

The Portable Variable Power Supply features a DC-output that can be easily changed by the user. As its name implies, this power supply is portable, making it invaluable in various circuit projects.
