DEMO 1 - Slide the mouse over the gray rectangle to see how increasing the load resistor RL affects the output voltage VL.
DEMO 2 - Slide the mouse over the gray rectangles to see how the values of RL and RTH affect the output voltage VL.
DEMO 3 - Slide the mouse over the gray rectangles to compare how VL depends on RL with how it depends on RTH.
