Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.
Parallel Circuit Analysis Practice Problems: Circuit #6
By Patrick Hoppe
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
Interlocking Ladder Diagrams
By Terry Bartelt
Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.
By Weldon Faull
Learners read how kanban is used in production control.
Series Circuit Analysis Practice Problems: Circuit #6
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
