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
