### Insertion of current carrying metal sheet between the plates of parallel plate capacitor

A parallel plate capacitor with area of plates A and distance between them d is charged with Voltage V1. A metal sheet carrying current is inserted between the sheets. How does the system change? What'...

### How can a conductor plate stay neutral when we force it to be charged?

At the beginning of this video "Capacitors and Capacitance: Capacitor physics and circuit operation" Let say, blue particles be negative charges. In the video, it is claimed that If we push electrons ...

### Current in a RC circuit

In order to find current in an RC circuit, resistance of only the resistor is considered i.e. $I_\text{resistor} = V_\text{resistor} / R$. Why is the reactance of the capacitor not considered? The ...

### Partial discharge of capacitors - can it be engineered to give a desired, continuous output?

Don't know anything about physics. I expect to be ignored or told to go somewhere else. My question is on converting energy stored in a capacitor by engineering controlled partial discharge (leakage,...

### Electric field in capacitors

As many of you may know, a capacitor stores energy by means of the electric field crested between the plates of this capacitor, but how is the electric field able to store the energy itself?
