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.

Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.

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.

In this interactive object, learners answer nine questions about inductors.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
