Transformers and Turn Relationships
This is lab 9 of 10 in the course
In this lab, students will learn about transformers. Transformers are devices that use electromagnetic induction to increase and decrease the voltages of AC signals. They allow us to manage the logistics of power transmission and to establish a suitable voltage for each power use. The output of a transformer is determined by the ratio of turns in its two coils, also known as the turn relationship. Students will work with two different simulations in order to understand how a transformer's turn relationship affects voltage and current and to investigate transformer power efficiency.
