11. Other notable inventions include a variable resistor used in guided missiles and small component thick-film resistors for computers. 12. Asahi Pentax developed an additional lever on the lens which operated a variable resistor in the camera mount. 13. But the sensors, flexible strips of carbon-coated plastic that act as variable resistors , needed to be attached to something. 14. The Dynaco QD-1 Quadapter based on this idea, added a variable resistor to control the volume of the rear speakers. 15. If your variable resistor can dissipate less power than the fixed resistor, it may overheat when it is at a similar value. 16. In recent years, electronic speed controllers ( ESCs ) have been developed to replace the old variable resistors , which were extremely inefficient. 17. The static pressure inside the chamber was used to control the degree of collapse of the tube, so providing a variable resistor . 18. Variable resistors can also degrade in a different manner, typically involving poor contact between the wiper and the body of the resistance.19. At any point in time, Ohm's Law will apply, just as it applies when a variable resistor is included in a circuit. 20. Also the data lines are asynchronous so make sure it's not oscillating before addressing it to the resistors ( or variable resistor ).
