Learners read how to use the arctangent function to calculate the theta of an angle. The proper keystrokes are displayed.

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.

Learners view the operation of an NPN transistor in the active region.

Students examine the first and second approximations of a voltage source. A "stiff" voltage source is defined, and several examples are given.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.

Tic-Tac-Toe Game of Ergonomic Principles (Ref: Ergonomics: The Study of Work OSHA 3125)

Squidhunter is a single player multiple choice question/answer game. The player uses the directional arrows to control the pirate and the spacebar to fire harpoons at the enemy squids. Collect treasure by killing squids and answering correctly. Wrong answers will lower the player's score.
