Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this learning activity you'll calculate the total inductance of a series circuit.

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

This animated guide presents an FAA map and aerial photos showing various areas of interest to student pilots enrolled in flight training at FVTC Aviation at Wittman Regional Airport in Oshkosh, WI. The airport is the site of the annual Experimental Aircraft Association's AirVenture Oshkosh. This object has sound.

Learners examine the various classifications of airspace and the requirements to pilot an aircraft there. A quiz completes the activity. This object has sound.

Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.
