For Teachers
Variable Resistor JavaScript Simulation Applet HTML5
Instructions on how to use Simulation Applet
Variable Rheostat
Step 1: Drag the rheostat triangle
Dragging it to the right will increase the number of triangles.
Dragging to the left will do the opposite effect.
Step 2: Check the ammeter for the reading.
The ammeter needle will move depending on the position of the triangle.
Toggling Between Views
There are three types of views in this simulation:
(World View)
(Diagram View)
(Special View)
Toggling between the combo box will select the varying views as shown above.
Dimmer Button
Step 1: Turn the knob on the left to adjust the brightness of the bulb
Reset Button
Resets the whole simulation by clicking.
