Analog Position Control (Screencast)
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.
