Rotary potentiometers. Potentiometers are a type of variable resistor. On rotary potentiometers such as this turning the shaft (silver,upper centre) varies the resistance to electric current across the metal contacts (silver,lower centre). Potentiometers are used in devices such as light dimmers and volume controls | |
