Then, what will be the numerical value of charge on each plates of the capacitor.


Given In

An electron enters a parallel plate capacitor with horizontal speed and is found to deflect by angle on leaving the capacitor as shown. It is found that and gravity is negligible.
If the initial horizontal speed is doubled, then will be:

The material filled between the plates of a parallel plate capacitor has resistivity . The value of capacitance of the capacitor is . If a potential difference of is applied across the plates of the capacitor, then the value of leakage current flowing out of the capacitor is: (given the value of relative permittivity of material is )

Find the total capacitance and total charge on the capacitors

As shown in the figure below, if a capacitor is charged by connecting it with resistance then energy given by the battery will be

In the figure is shown a system of four capacitors connected across a battery. The charge that will flow from switch S when it is closed is:



What are the charges stored in the and capacitors in the circuit below, once the currents become steady?

Two identical parallel plate capacitors of capacitance each are connected in series with a battery of emf, as shown. If one of the capacitors is now filled with a dielectric of dielectric constant , the amount of charge which will flow through the battery is (neglect internal resistance of the battery)
