This animated lesson shows how a pressure switch connected in a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.

In this animated object, learners follow a process for troubleshooting digital integrated circuits on a printed circuit board using a logic probe.

In this interactive and animated object, learners examine the duty cycle of a squarewave produced by a multivibrator using a 555 IC (integrated circuit). A brief quiz completes the activity.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.

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.
