Learners work practice problems to calculate the total resistance of a circuit. Feedback is provided.

The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.

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

This primer introduces the student to the correct method of using the log function on a TI-86 calculator.

Picture of Adira hydraulic shear's operator's panel with part identification and instructions on how to start and stop the shear as well as setting stroke (cutting length).
