Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.

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

Students read an explanation of power factor correction. Examples of both inductive and capacitive loads are given.

Students follow step-by-step instructions to learn how to use the SIMULT function on this scientific calculator.

This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

In this animated activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.

In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.

Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this interactive object, learners examine how hydraulic oil is contaminated, the types of damage contamination can cause, and the methods used to clean the oil.
