Mathematical Expression: To determine the energy present in an assembly of charges, we must first determine the amount of work necessary to assemble them. Where this energy is stored is immaterial. However, I don't know if there are more solid grounds for accepting this (a proof or experimental evidence) in general relativity: I hope someone else can comment on this. 0000006847 00000 n Much like the gravitational pull of the the earth attracts a particle if we increase its height by $h$ (potential increases) and the energy is stored in the body. )��b�f�s��� ���gd�J��t��G�F#�!��w,�mX�؀��6g�fڐ➌������Ц��A�s�T���fD���;GV���ssx���)�)}�,c2sdL�',�9��U�pL�\>���FV���ɲ\��Α�\w�ry���cz\Y�����W��I9}L��]�c�r�^U9�\�'������*Wv��+�{�r���W�q�I��k�Y�=�a��cNת��9].o�ӥHM�+���px�gk����W���ӭ���jA:F�8>O)��k���`���Q�������u�g� v�^x��Nr_x��RT��1M)ľG8SN8݂A�`�pt�ܘ�eg�H!u�I�Bh����n��5l�`�x�h7RD�3�F��QT�q�d�)���~�E�� �Žf�&�B$/���ד�����*d\.���'e)_�i=�!^ �n��ㇸ ����J�Y �z=U%�� ��!Q�sIΜ�v9�/Ί����K�H�g�}P퐊`M��U�:�~ �U9y � ��b5O5��jF�J��*�Jl�d�:� J�!�4G�|��L�0���������{Ǥs�&�Rhi�g�ˡ�1q�6��N���v$���R�+.

This last part made no sense to me,the energy supplied is to do the work and the energy goes into the capacitor. Even when there are two small equal and opposite charges, when one charge is pushed away from the other, the potential of the charge increases and it is stored in the charge not in space. 1.5. }$$ But in electrostatics one could just as well say it is stored in the charge, with a density $\frac{1}{2}\rho V$.

Even with individual charges you can consider the energy as being stored in the field. In the context of radiation theory (Chapter 11) it is useful (and in general relativity it is essential) to regard the energy as stored in the field, with a density $$\frac{\epsilon_0}{2}E^2 = \text{energy per unit volume. 0000009340 00000 n Energy density in electrostatic fields.
