WebbPotentiometers. Potentiometers and Rheostats create a change in their resistive value when a connected shaft is physically rotated. Resistors provide a fixed value of resistance that blocks or resists the flow of electrical current around a circuit, as well as producing a voltage drop in accordance with Ohm’s law. WebbTPS is usually located on the throttle valve spindle so that it can directly monitor its position. The TPS sensor is a potentiometer, providing a variable resistance depending on the position of the throttle valve (and hence throttle position sensor). The sensor signal is used by the engine control unit (ECU) as an input to its control system. flitsmeister accountWebbObjective. In this laboratory we continue our discussion on operational amplifiers (see the previous lab here: Activity 1. Simple Op Amps) focusing on variable gain / voltage-controlled amplifiers. Most operational amplifier or op-amp circuits have a fixed level of gain. However it is often useful to be able to vary the gain. great gaming mice
