Learners examine first and second approximations and view examples of a "stiff" current source.

Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.

The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.

In this animated object, learners examine the basics of capacitance and capacitors.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
