The Role of Transformers and Their Efficiency

Transformers transfer electrical energy from one circuit to another through inductively coupled coils, typically wound around a core. They can increase or decrease voltage levels by varying the number of turns in the coils, making them useful in power distribution and electronic devices. Transformers are generally very efficient, with high levels of energy transfer and minimal losses. Inductors, on the other hand, have parasitic resistance that leads to energy losses, primarily in the form of heat. Both transformers and inductors play crucial roles in electronic and electrical systems, with transformers impacting the size, weight, and performance of systems, while inductors are essential components in power supply, noise suppression, and signal frequency applications.
