Energy in Transformers

In an electric circuit, the rate of energy transferred to components (power) is equal to the current multiplied by the potential difference.

100% efficient transformers

  • In a transformer that is 100% efficient, all of the energy transferred to the transformer by the primary coil will be transferred to any components connected to the secondary coil. Therefore, the power in the primary and secondary coil will be equal.
