Apr 02, 2021 · Download LTspice File - Capacitor_Energy_Via_Integration.asc (718 Bytes) Since V(Vout) is the voltage across the capacitor C1, then the instantaneous power of C1 is *V(Vout)I(C1) as shown in light blue of the top plot. The transfer function can be derived with the help of the Superposition Theorem. This theorem says that the effect of all sources in a linear circuit is the algebraic sum of all of the effects of each source taken separately, in the same circuit. In other words (back at Figure 1), if we remove V1, and replace it with a short circuit to ground ... Create sine wave LTspice can create simulate and plot the signal of the sine wave. 1.
