In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current and power. A help screen is provided.

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 by each resistor.

In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.

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

In this interactive object, learners read a brief summary of the principles of cash basis accounting and then check their knowledge of transactions in a drag-and-drop exercise.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
