The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.

This animated lesson demonstrates hydraulic pressure switch applications when the switch is connected to a ladder circuit to operate in a hydraulic system.

In this learning activity you'll review the steps for determining the total capacitance of a parallel circuit and work practice problems.

In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.

In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.

In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.

In this learning activity you'll determine the total resistance in a DC parallel circuit.

In this learning activity you'll practice solving for the total resistance of series-parallel DC circuits.
