The efficiency of a transformer is a measure of how effectively the transformer can transfer electrical power from the input circuit to the output circuit.
It is defined as the ratio of the output power to the input power, and is usually expressed as a percentage. In other words, the efficiency of a transformer is the amount of electrical power that is actually delivered to the load, relative to the amount of power that is supplied to the transformer.
An efficient transformer will have a high efficiency, meaning that it will waste very little power in the form of heat or other losses, and will deliver most of the electrical power to the load.
