    The core of transformer is laminated to reduce the effect of

    A)  copper losses   

    B)  flux leakage

    C)  hysteresis loss  

    D)  eddy current

    Correct Answer: D

    Solution :

     Some electrical power is wasted in the form of heat due to eddy currents induced in the core. To minimize this loss transformer cores are laminated and silicon is added to the core material as it increases the resistivity.
