One method used to increase the overall capacitance of a capacitor while keeping its size small is to “interleave” more plates together within a single capacitor body. Instead of just one set of parallel plates, a capacitor can have many individual plates connected together thereby increasing the surface area, A of the plates.
But the stronger electric field is not the reason for the larger capacitance C C in the constant voltage case, the larger capacitance is due to the decreased distance d d between the plates independent of the voltage across (consider the increase in capacitance in the case that the voltage V V across the capacitor is the constant V = 0 V = 0).
The question should rather be "what made the capacitor have larger than rated capacitance". Electrolytic capacitors have a thin oxide layer as dielectric. When they are not being used for a long time this layer shrinks, making for higher capacitance and lower maximum voltage.
When looking at capacitance several different sources say that circuits might malfunction or burn with higher capacity capacitors than designed with. Unfortunately, but none of those sources go into detail. How can a capacitor cause malfunction if capacitance increases? Wouldn't the capacitor simply take longer to fully charge?
So conceptually, if a capacitor is connected to a voltage source, and if you decrease the distance between two plates, the electric field in between the plates increases. This means that you can hold more charge on each plate because there's more force there now, increasing the capacitance.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
In a parallel plate capacitor, the capacity of capacitor, C = d k ε 0 A ∴ C ∝ A So, the capacity of capacitor increase if area of the plate is increased. All India Exams NEET
