A transformer obeys the Law of Conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another. This means that the electrical power input to the primary coil is ideally equal to the electrical power output from the secondary coil, with voltage and current inversely proportional to maintain a constant power level.
