Description : In a transformer the resistance between its primary and secondary should be?
Last Answer : In a transformer the resistance between its primary and secondary should be infinity.
Description : State why a transformer always have an efficiency of more than 90%.
Last Answer : As transformer is static device with no moving parts, the losses due to friction & windage are completely absent. Hence transformer has efficiency of more than 90%.
Last Answer : An ideal transformer will have maximum efficiency at a load such that copper loss equal to iron loss.
Last Answer : A transformer can have regulation closer to zero on leading power factor.
Last Answer : Material used for construction of transformer core is usually silicon steel.
