Right click the graph and left click to edit its start and stop times (Fig 11):
We want to see the initial transient, so leave “Start time” at 0 and set “Stop time” to some value (100 ms has been chosen - later try some other values). Click OK to accept.
Place the cursor over the graph and press space bar to run the simulation. Provided you have connected everything together properly (not left wires off nodes etc.) then a trace will appear on the graph. Now click in the green bar on the top of the graph to expand it to full screen (fig 12).
Take measurements of the ripple by right clicking - a measuring line will appear. As you move the position of the measuring line time and voltage are updated at the bottom of the window.

How do these values compare to the expected values?
