Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
The learner will understand the operation of motor control circuits used to start and stop three-phase motors.

Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.
