Transformers are electrical devices with the capacity to change the voltage level of an alternating current (AC) in a circuit. They function only with AC circuits, not with direct current (DC) circuits. The basic components of a transformer are two separate coils of wire wound around a single core. The coil connected to the incoming or voltage source is the primary coil, the coil connected to outgoing or voltage output is the secondary coil, and the core is an electromagnetic device that impedes (limits) or amplifies (increases) voltage flow according to output requirements.
A more in-depth investigation into how transformers work, their various types, and their common applications helps provide a greater understanding of the critical function they serve in providing usable power to operate computers, appliances, lighting fixtures, and a wide range of other electrical and electronic devices.
