Learners read how to use the arctangent function to calculate the theta of an angle. The proper keystrokes are displayed.

Students view the steps to follow to add complex numbers in Excel.

Students follow step-by-step directions on how to make mathematical calculations for a Wheatstone bridge.

This animated lesson shows how a ladder circuit uses timer-on delays to cause an extrusion machine to operate.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency is increased above resonance.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
