Confusingly, I believe it''s the reciprocal 1/C that corresponds to the spring constant so a stiff spring is like a weak capacitor. For a given applied force (voltage), a stiff, high-k spring will displace very little (weak, low-C capacitor will store very little charge) and store 1/2kx 2 energy in the spring (Q 2 / 2C in the cap) . I also think of the resonant frequency as a mnemonic; spring ...

What is a resistor and a capacitor?
A capacitor works on the principle that the capacitance of a conductor shows increase when an earthed conductor is brought near it. Therefore, the capacitor has two parallel plates facing each other in opposite directions and are separated by some distance or gap. Do capacitors have resistance? The resistance of an ideal capacitor is infinite.

Placing a "bypass" capacitor as close to the chip''s supply pins as possible provides an AC short to fix this.

What Is a Capacitor and What Is It Used For?
As a direct current flows into a capacitor, it charges with energy and releases an alternating current flow back into the circuit. Most capacitors have a positive and negative terminal in the form of legs, pads, or plates. Current flows into one of these legs, through the capacitor''s body, and out of the other leg.
