Students view a demonstration of Kirchhoff's Current Law (KCL) using complex numbers with respect to ac.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.
