Students view the steps, symbols, and benefits of creating a process flowchart. They then perform a self-assessment to determine their level of understanding.
In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.
In this animated object, learners examine the ratio control method used in automation when two or more ingredients are mixed. A brief quiz completes the activity.
In this interactive object, learners follow the litigation process from the filing of a court case through the filing of an appeal. Learners’ choices will move the case in different directions, based on the actions of the parties and the Court. A quiz completes the activity.
Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
Learners read about the vector diagram for a parallel RC circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.
In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions
Learners examine the main characteristics of the four financial statements required in accounting: the income statement, the owner's equity statement, the balance sheet, and the statement of cash flow.
Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.
