Figure 1e : Fig. 1a circuit constructed in PSpice<br />

The result of a time (transient) analysis so as to watch a few cycles of the sinus wave appears as in Fig. 1f.<br />

current)<br />

It is possible to apply superposition in Fig. 1e just by entering zero voltage value for either source instead of<br />

replacing them with a short circuit:<br />
