What is offset current
Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.
Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
The inverting amplifier configuration is presented. The closed loop voltage gain and the closed loop bandwidth formulas are explained, along with the concept of negative feedback.
