Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
Learners read an analogy comparing an electrical transformer to mechanical gears.
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.
Students read an introduction to transformers that includes schematic symbols, turns ratios, mutual inductance, and the coefficient of coupling.
