The throttle position sensor changes the resistance. Why does it output a changing voltage signal?

The throttle position sensor is a sliding resistor, and the equivalent circuit is two resistors in series. A fixed voltage (5V) is applied to both ends of the two resistors, and a signal is obtained at the connection point of the two resistors. Changing the throttle position is equivalent to changing the resistance values of the two resistors, resulting in a change in the voltage drop at the junction of the two resistors.
