Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.

Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.

The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.

In this learning activity you'll review the various ways to calculate the total power consumed in a series circuit.

Learners read an explanation of how to troubleshoot a faulty digital-to-analog converter that has a shorted input.

In this video, you’ll explore how to use a vise on a Bridgeport mill to securely hold your workpiece.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

Learners review Kirchhoff's Current Law and work six practice problems. Feedback is given.

The learner will identify the steps and proper techniques for installing a wire spool on a welding machine.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.

Learners are introduced to the maximum power transfer theorem. Examples show the load as it varies and the results are graphed.

In this video, we’ll go over the necessary steps to square the toolhead on a Bridgeport mill.

In this learning activity you'll follow 11 steps to take measurements using a Vernier caliper.
