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.
The learner will calculate and select the proper cutting speeds for various drill press operations.
