Rheostat. A rheostat is a variable resistor. A resistance wire is wound around a cylinder,and a moveable contact may be slid along the coil. The further along the coil,the higher the resistance. If both ends of the coil and the contact are connected to a circuit,the rheostat becomes a potentiometer or voltage divider | |
