Variable Resistor. This element adds resistance to current flow in circuits. Place up to ten variable resistors in the simulation window. With the Select tool, you can move and rotate variable resistors, and wire them to other objects. You attach wires to the variable resistor's two nodes, which are indicated by the yellow rectangles in Figures 1 and 2.

The default resistance of the variable resistor is 100 ohms. You can change this resistance in one of two ways. In the variable resistor's Properties Box, you can set the resistance between 1.0 and 100,000 ohms. You can also change the resistance manually in either Run mode or Stop mode.

To change the resistance manually, click on the hotspot indicated in Figures 3 (Realistic mode) and 4 (Schematic mode). To decrease resistance, drag the hotspot clockwise (Figure 5). To increase resistance, drag it counterclockwise (Figure 6). Dragging the hotspot around 360º changes resistance by 360 ohms.
