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.

in this case of a few tens of pF and suitable as a low-power trimmer capacitor or in a single-chip FM radio. Rather than make a set of interlocking vanes as you’d find in a commercial design ...

But do you know why? [Bertho] put together a great post that looks that the benefits of using decoupling capacitors in your circuits. He set up a circuit using a 74HC04 inverter and put it to the ...
