| This means that only half of the energy emitted by the source is stored in the capacitor! Again, this doesn't really sound comprehensible at first. Again, it helps to look at small packets of charge that have to be transferred from the ideal source to the capacitor. <imgref imageNo06 > shows current and voltage waveforms across the capacitor and the stored energy for different resistance values. There, too, it can be seen that the maximum stored energy (dashed line in the figure at right) is given by $\Delta W= {{1}\over{2}}$ alone. $U_s^2 \cdot C = {{1}\over{2}} \cdot (5V)^2 \cdot 1 \mu F = 12.5 \mu Ws$ is given. | This means that only half of the energy emitted by the source is stored in the capacitor!
