| Abstract: | The changes of energies stored in two capacitors with initial voltages or two inductors with initial currents while connected in a circuit are discussed in an analogous way.The effects of directions of the initial voltages or currents on the changes of energies are also investigated,in hope of understanding electromagnetic phenomena in a deeper way. |
