Elastance
Heater.

Despite having a degree in physics (1979) and being in and around electronics since I was 10 (Philips Electronics kits anyone?) I have just made a stunning discovery:
Elastance - The voltage across a capacitor after accepting an electric charge of 1 coulomb.
Unit of measurement, the daraf (Farad backwards).

All these years I've been using "elastors" in my circuits and never knew it:)
That is very big elastors for decoupling ICs and tiny elastors for power supply smoothing.

The title was such a come-on, I was hoping for more, like an elastic sheet, conductive on both sides and insulated in the middle. Upon stretching, the two surfaces would become closer together, causing the capacitance to increase and the charge-induced voltage to fall. An elastor!
But no: elastance:capacitance::conductance:resistance. In trying to figure out where they came up with that name, I'm imagining a balloon being filled with water (charge). The higher its elastance, the more it has to stretch to accommodate a fixed volume of water. And the more it stretches, the higher its internal pressure (voltage) will be.
Well, okay, that's kind of a stretch.
