Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

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 interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

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

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.
