Making of a Rheostat

Making of a Rheostat

A small device that controls the voltage flow by a dial or knob.

What Do You Need?

  1. A flashlight bulb and socket
  2. Two “D” cell batteries or a dry cell lantern battery
  3. About 16 inches of wire
  4. A piece of wire about 2 inches long
  5. A long, long spring — the spring from a inside w roll up window will work great. You’ll need to break open the wooden section that the shade rolls up on to get to the spring. Ask an adult to help you get this spring out.
  6. Pair of wire clippers
