A capacitor is used to store electrons (electricity) for use in a circuit. Capacitors are made up of two conductive materials separated by a dielectric. The dielectric material varies. Paper, plastic, oil, ceramic, resin or epoxy and air are all materials used as a dielectric in a capacitor.
What is the electric field in a parallel plate capacitor?
When discussing an ideal parallel-plate capacitor, $sigma$ usually denotes the area charge density of the plate as a whole - that is, the total charge on the plate divided by the area of the plate. There is not one $sigma$ for the inside surface and a separate $sigma$ for the outside surface. Or rather, there is, but the $sigma$ used in ...

Why does a capacitor create a 90 degree phase shift of voltage …
Let the voltage source be a constant voltage, V. The charge on the capacitor is therefore constant (Q = CV). Now lets say the voltage changes. The charge on the capacitor must also change, therefore some current flows to add or remove charge. The amount of charge that moves is therefore proportional to the change in voltage.

Why does capacitor voltage lag current?
$begingroup$ How is it possible that at t=0 current is present without voltage? Well, remember that what is plotted is the voltage across the capacitor, not the voltage across the resistor. In fact, there is voltage across the resistor! For a resistor, current can only be present if voltage is simultaneously across the resistor; for a capacitor, this isn''t always true.
Representation of AC Current And Voltage By Phasor Diagram
The length of the vector represents the peak value of the voltage or current. The angle between the voltage and current vectors is the phase difference. For a capacitor, the current vector is 90 degrees ahead of the voltage vector, indicating that the current leads the voltage by 90 degrees.
