Rheostats are mostly wire wound. Hence, rheostats are also sometimes referred as variable wire wound resistors. Generally, rheostats are made by winding the Nichrome wire around an insulating ceramic core. The ceramic core of the rheostat acts as the insulating material to the heat.
How do you make a rheostat?
- Cut the 16 inch wire in half and attach each piece to the open end of the joined batteries.
- Connect the free end of one wire to one terminal of the light socket. Connect the other free wire to one end of the spring.
- Connect the two-inch long wire to the other terminal of the light socket.
How does a rheostat work?
How does a rheostat work? The basic principle that rheostats use is Ohm’s law, which states that current is inversely proportional to resistance for a given voltage. This means the current decreases as the resistance increases or increases as the resistance decreases.
