how do power company transformers work?

Power company transformers work by converting high-voltage electricity from power plants into lower voltages suitable for distribution. They operate on the principle of electromagnetic induction, using two coils of wire (primary and secondary) wrapped around a magnetic core. When alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. This allows efficient transmission of electricity over long distances while minimizing energy loss.
