Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.

Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.

In this learning activity you'll practice solving for the total resistance of series-parallel DC circuits.

In this interactive object, learners adjust the caster of a vehicle to control its directional stability.

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

In this animated object, learners read the dimensions of the different types of vehicles typically considered in highway design.
