$begingroup$ Hi, I wonder if we should take the induced charge into account when calculating the electric field by superposition. If we isolate the positive plate without changing its charge distribution, then the electric field due to it alone is E+ = Q/Aε0 (twice that of a conducting plate due to the induced charge).

Larger capacitors typically have larger voltage ratings and hence cool down faster. It could also be due to age (caps shrink with age) or manufacturing capability. In most circumstances, the physical size of the capacitor is directly proportional to the voltage rating. ... If a capacitor is larger, its charge/discharge rate will be slower.
The current is driven by the potential difference across the capacitor, and this is proportional to the charge on the capacitor, so when the current gets down to 60% of its initial value, that means that the charge on the capacitor has dropped by the same factor.
If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the closer they are. If the distance becomes too large the charges don''t feel each other''s presence anymore; the electric field is too weak.
The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28) the size of a football field could hold a lot of charge without requiring too much work per unit charge to push the charge into the capacitor.
Thus larger the area of the plates more is the charge and greater the distance of separation between the plates lesser the charge on the capacitor. Parallel Plate Capacitor Figure 1.parallel plate capacitor circuit.

In quantitative terms, the capacitance is the charge per unit voltage that can be stored by an element. The capacitance of a capacitor can be imagined as the volume of a water bottle. The larger the bottle, the more water it can store; similarly, the larger the capacitor, the greater will be its capacitance value.
(a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.

The previous example highlights the difficulty of storing a large amount of charge in capacitors. If d d size 12{d} {} is made smaller to produce a larger capacitance, then the maximum voltage must be reduced proportionally to avoid breakdown (since E = V / d E = V / d size 12{E=V/d} {}).

Thus the charge on the capacitor asymptotically approaches its final value (CV), reaching 63% (1 -e-1) of the final value in time (RC) and half of the final value in time (RC ln 2 = 0.6931, RC). The potential difference across the plates increases at the same rate. Potential difference cannot change instantaneously in any circuit ...
By definition, a 1.0-F capacitor is able to store 1.0 C of charge (a very large amount of charge) when the potential difference between its plates is only 1.0 V. One farad is therefore a very large capacitance. ... The amount of charge a vacuum capacitor can store depends on two major factors: the voltage applied and the capacitor''s physical ...

As charge increases on the capacitor plates, there is increasing opposition to the flow of charge by the repulsion of like charges on each plate. In terms of voltage, this is because voltage across the capacitor is given by V c = Q / C V c = Q / C, where Q Q is the amount of charge stored on each plate and C C is the capacitance .
Squeezing the same charge into a capacitor the size of a fingernail would require much more work, so V would be very large, and the capacitance would be much smaller. Although the …
The result of a larger plate area is less charge stored for the same applied voltage, which means that the capacitance is smaller. True. ... Mica capacitors are often used for large capacitance values of about 100 to 5000 uF. True.

A capacitor with a large capacitance is able to store more charge per voltage difference.
