In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this learning activity you'll review safety considerations for using hydraulic press brakes.

This document is a visual and text description of preparing thread cutting tools, primarily used on a lathe.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.

Users read work instructions and view a drawing and calculations for turning on a lathe using a digital readout.

Students follow steps to determine the number of inputs that can be driven by a specific IC. A sample problem is given.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.
