In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.
This animated object allows students to examine the four steps used to reduce a complex circuit to a simple series circuit.
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
Review types of heat transfer

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
Learners read a passage and answer two questions based on the information found it that passage. Immediate feedback is provided.
Determine the different transformations.
