The efficiency of a real transformer is not 100% due to various factors such as resistance in the windings, core losses, and leakage flux. Resistance in the windings causes energy losses in the form of heat, reducing the efficiency of the transformer. Core losses, which include hysteresis and eddy current losses, also contribute to energy dissipation. Additionally, some of the magnetic flux generated by the primary winding may not link completely with the secondary winding, leading to leakage flux and further reducing the efficiency of the transformer. **

Graduation certificates typically do not have the same level of security features as official documents like passports or driver's licenses.
