[PhysicsGirl] posts videos that would be good to use in a classroom or homeschool environment. She recently showed a 200KV capacitor made from a cake pan, a bowl, and some other common items (see ...

Capacitors are small devices used to store electric charges and consist of one or more pairs of conductors separated by an insulator. They’re mainly used in energy-storing devices such as televisions, ...

Many electronic devices require user input for setting the application properties. Typical input devices include pushbuttons, potentiometers, and touchscreens. To minimize overall project cost, you ...

Current capacitors often require dedicated cooling loops to keep them operating within a safe temperature range. If the capacitor itself can withstand the heat of an engine block or a high-voltage ...

If you build electronic circuits on a regular basis the chances are you will have used capacitors many times. They are a standard component along with the resistor whose values are lifted off the ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Switched-capacitor blocks are easily configured to be integrators. When configured as an integrator, a switch-capacitor block can function as an op amp. Closed-loop stability is achieved by ...
