6 FAQs about [Why do conductors act as capacitors ]
What happens when a capacitor is connected to a power source?
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
What happens when a voltage is applied to a capacitor?
When a voltage is applied to a capacitor, it starts charging up, storing electrical energy in the form of electrons on one of the plates. The other plate becomes positively charged to balance things out. This charge separation creates a voltage potential between the two plates and an electric field between the plates, storing the energy.
Why do capacitors have two conducting plates separated by an insulator?
As we've already seen, capacitors have two conducting plates separated by an insulator. The bigger the plates, the closer they are, and the better the insulator in between them, the more charge a capacitor can store. But why are all these things true? Why don't capacitors just have one big plate?
Is a pair of conductors separated by a dielectric a capacitor?
Yes, any pair of conductors separated by a dielectric is a capacitor. Arranging the conductors as parallel plates will increase the capacitance since it is proportional to surface area. The wikipedia page shows how to calculate the capacitance of different geometries (you can verify the calculations in one of the referenced textbooks).
Why do electrons go into a capacitor?
Rather, the electrons redistribute themselves so that the potential difference (voltage) is the same everywhere in that half of the circuit. Most of the excess electrons end up in the capacitor, precisely because this is where the electric field is strongest.
How are capacitors formed?
REVIEW: Capacitors are formed by creating two layers of conductors separated by an insulator. Capacitors smooth out ripples and act as open circuits in DC applications. Capacitors act as conductors in AC circuits as the frequency continues to increase.
