The circuit he’s building here is a solar charger for the super capacitor. Being a fairly small device there’s not a lot of current, voltage, or energy, but these are different enough from ...

There has been work on laying out linear capacitors on IC substrates using fractals ... I was thinking about building up a circuit to test when I realized I should search Hackaday first.

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...

As a result, for stable operation in continuous-conduction mode, the application circuit's output capacitor is normally a high-ESR tantalum type for two reasons. The portion of output ripple due to ...

Capacitors play three important roles in an electronic circuit: charging and discharging ... known modern application for diodes is in light-emitting diodes (LEDs). These use a special kind of doping ...
