Guided Notes
3 key concepts
- 1
A transformer is an electrical device that uses electromagnetic induction to change the voltage of an alternating current without changing its frequency.
- 2
A step-up transformer has more turns on the secondary coil than the primary coil, while a step-down transformer has fewer turns on the secondary coil.
- 3
Transformers only work with alternating current (AC) because they rely on a constantly changing magnetic flux to induce voltage in the secondary coil; they do not work with direct current (DC).
