9.The core of a transformer is laminated so that-(1) ratio of voltage in the primary and secondary maybe increased(2) energy losses due to eddy currents may beminimised(3) weight of transformer may be reduced(4) rusting may be prevented |

Answer» Thecoreislaminatedto reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. The eddy currents cause energy to be lost from thetransformeras they heat up thecore- meaning that electrical energy is being wasted as unwanted heat energy. The answer is energy losses due to eddy currents may be minimised. |
