AC Transformers - Wolfram Demonstrations Project

AC Transformers - Wolfram Demonstrations Project: An electrical transformer is a device to change the voltage and amperage of alternating currents In the simple design shown here primary wire coils blue and secondary coils red are wound around a ferromagnetic core An alternating current in the primary circuit creates a timedependent magnetic field in the core which in turn induces an alternating current in the secondary circuit via Faradays law o
