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.
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
The learner will calculate and select the proper cutting speeds for various drill press operations.
