Noobish question. I''m trying to make a dc variable voltage power supply. I will include the schematic which I am trying to build. In the schematic there are two 1000 uf capacitors which I believe are used to smooth out the peaks of the dc voltage before hitting the regulator, but I am confused because in the schematic it shows them being grounded.

About Photovoltaic Energy StorageQuestion: A parallel-plate capacitor is connected to a 10 V power supply. If the distance botween the platos is decreased but the voltage is kopt at 10 V, how does this affect the oloctric feld betweon the plates? The electric lieid does nat change. The electric field increases. The electric field decreases:
About Photovoltaic Energy StorageAn uncharged capacitor is connected to a power supply, in series with a resistor, as shown in the diagram, and current begins to run in the circuit. The square plates of the capacitor have dimensions 2m times 2m, and are separated by a gap of 0.5 mm. filled with air. The resistor has resistance 300 Ohm, length 10 cm, and radius 5 mm.
About Photovoltaic Energy Storage0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of ...

About Photovoltaic Energy StorageWith my understanding, circuit ''A'' will quickly accumulate negative charge on the lower plate and an equal amount of positive charge on the upper plate. In circuit ''B'' I am less clear on what the difference would be given the power supply is still connected. If the net charge on the plates is the same, are there any other expected differences?
About Photovoltaic Energy StorageAdded: Nils noted: A very large reservoir capacitor may lead to increased noise. The on-time of the diodes would get shorter yet the same amount of power is transferred. This causes current spikes in the transformer which start to radiate out a …

About Photovoltaic Energy StorageCharging. Capacitors are charged by a power supply (e.g., a battery); One plate of the capacitor is connected to the positive terminal of the power supply . The positive terminal ''pulls'' electrons from this plate; Hence the plate nearest the positive terminal becomes positively charged; These electrons travel around the circuit and are pushed …

About Photovoltaic Energy StorageYour reasoning of a change in charge density is about right. If you push an electron onto one plate of the capacitor, the charge density there will necessarily rise, but in doing so, the increased negative potential of that plate will repel an electron out of the other plate, thereby reducing the charge density on the other side of the dielectric.
About Photovoltaic Energy StorageThey are connected to the power supply. The plate, connected to the positive terminal of the battery, acquires a positive charge. On the other hand, the plate, connected to the negative terminal of battery acquires a negative charge. Due to the attraction charges
About Photovoltaic Energy StorageOne possibility for supplying small loads from the AC power supply that is not only elegant, but also simple and cost-effective, is to connect the capacitor and load in series. This makes use of the otherwise unwanted effect of phase shift: The voltage arrives at a capacitor with a 90-degree phase shift from the current; the capacitor acts as a …
