The power connector is PJ-007, and the terminal block is 282834-2. We will also need to connect the power connector and a two-pin terminal block for the battery. Now, repeat the process with all the other components from the schematic. The window will close, and the Component will be placed wherever you left-click in the schematic area. To place the Component, select the one that you want and click Ok. You should pay attention to the footprint, as you are going to use it in your layout. There will be different versions of the same Component. The figure below shows the essential information about this window. You can type the Component that you want or go to the Group dropdown menu. The “Select a Component” window will open. For that, you can either go to Edit tab -> Component or press ctrl+w. Once you open Multisim, the first thing is to add the components. This circuit is usually used for a Lead-acid 12V battery. In the figure below, we have a current controlled battery charger circuit using LM317.
