In this learning activity you'll explore the effect of connecting voltage sources in series to increase voltage applied to a load.

In this learning activity you'll understand what flow charts are and how they're used to create computer programs.

In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.

In this animated activity, learners examine a systematic method for converting a decimal number (base 10) into a hexadecimal number (base 16).

In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.

In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.

The learner will learn the programming steps that are used to create circular motions with robots.

Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.

Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.

In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

In this animated activity, learners examine why various materials are conductors, insulators, or resistors of current. A short quiz completes the learning object.

In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.

This animated object allows students to examine the four steps used to reduce a complex circuit to a simple series circuit.

The learner will represent very large and very small numbers in engineering notation.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Students analyze the eight single variable Boolean theorems and their expressions.

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.

In this learning activity you'll explore the history behind gage blocks.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
