In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.

Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.

In this learning activity you'll review how a short affects current flow and voltage in a series circuit.

Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.

In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.

Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.

Students determine what happens to current flow in a series circuit when the resistance is changed. A brief quiz concludes the activity.

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
