In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.

This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.

This animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.

Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
