Students read an introduction to capacitive reactance and view examples.

This primer introduces the student to the correct method of entering complex numbers in both rectangular and polar form.

Learners examine a Filter-Regulator-Lubricator (FRL) unit that is used to prepare the air in a pneumatic system.

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 practice converting from one metric unit to another.

Learners consider why an impedance matching transformer is needed to connect an antenna to a television.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Use the definition to guess the word or prefix and save the moon!

This game will review primary, secondary, warm and cool color schemes.
