In this animated activity, learners read an explanation of the four different modalities (currents) used in electrotherapy.

Learners view two animations that show the effects of eddy currents.

Learners follow step-by-step instructions for creating a current-state map to identify how materials and information flow.

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.

In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.

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 interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.
