When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates. To gain insight into how this energy may be expressed (in terms of Q and V ), consider a charged, empty, parallel-plate capacitor; that is, a …

Kearey and Vine (1996) [1] have listed some compelling arguments in favour of the ridge-push/slab-pull model, as follows: (a) plates that are attached to subducting slabs (e.g., Pacific, Australian, and Nazca Plates) move the fastest, and plates that are not (e.g., North American, South American, Eurasian, and African Plates) move …
We shall start by supposing that the plates are isolated. In this case the charge on the plates is constant, and so is the charge density. Gauss''s law requires that ... (epsilon A/d_2) and the energy stored in the capacitor increases from (frac{Ad_1sigma^2}{2epsilon}text{ to }frac{Ad_2sigma^2}{2epsilon}). This energy …
[1] Earth''s subducting plates move 3–4 times faster than its overriding plates, but it remains unclear whether these contrasting plate speeds are caused by additional pull from subducting slabs or by increased viscous drag on the lithosphere-asthenosphere boundary beneath deeply-protruding continental roots. To investigate the …

To begin with, you have a neutral plate. But as you start to charge it, the plate accumulates electrons. These accumulated electrons are extra for the plate and makes the plates, as a whole, charged. Thus when you try to put more charge on the plate, the existing charges of the plate repel any extra charges.
If with the battery still connected, you pull the plates apart until their separation is now twice what it originally was, the capacitance of these plates, the energy stored in the capacitor, A 12.0 V battery remains connected to a parallel plate capacitor with plate area 0.284 m^2 and plate separation 3.94 mm. (a) What is the charge on the ...
The slab just fills the space inside the capacitor. The capacitor is charged by a battery and the battery is disconnected. Now the slab is started to pull out uniformly at t = 0. If at time t, capacitance of the capacitor is C. potential difference across plate is V, and energy stored in it is U, then which of the following graphs are correct?
Likewise, if no electric field existed between the plates, no energy would be stored between them. If we now disconnect the plates from the battery, they will hold the energy. We could connect the plates to a lightbulb, for example, and the lightbulb would light up until this energy was used up. These plates thus have the capacity to store energy.
Introduction to Capacitors, Capacitance and Charge
Slab-Pull. As a subducted plate descends into the mantle (see "convergent boundaries" below), the thick slab of primarily basaltic material (perhaps 100km, 40-60miles, thick!) undergoes mineralogic changes such that the slab becomes denser. ... because rocks cannot build up enough stress to release more energy. In contrast, divergent ...
