For a capacitor, we say that energy is stored in the field. This is understandable as the electric field is trying to combining the charges on the plates but there exists a physical barrier separating. In other words, I can say that the energy is stored as the electric potential energy of the charges in the two plates.
A: Energy is stored in a capacitor when an electric field is created between its plates. This occurs when a voltage is applied across the capacitor, causing charges to accumulate on the plates. The energy is released when the electric field collapses and the charges dissipate. Q: How energy is stored in capacitor and inductor?
A: Capacitors do store charge on their plates, but the net charge is zero, as the positive and negative charges on the plates are equal and opposite. The energy stored in a capacitor is due to the electric field created by the separation of these charges. Q: Why is energy stored in a capacitor half?
You are correct, that while charging a capacitor there will be a magnetic field present due to the change in the electric field. And of course B contains energy as pointed out. However: As the capacitor charges, the magnetic field does not remain static. This results in electromagnetic waves which radiate energy away.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
Another common application of a capacitor is Energy storage. But, does a capacitor store energy in the form of a magnetic field? No, a capacitor does not store energy in the form of a magnetic field.
