Answer 1

Given tables are From table 1.1 it is obvious that V - shaped w/bar on top core gives maximum transfer effect of electromagnetic effect to the secondary coil Though the transformer turns ratio N_2/N_1 = a = 1, But voltage ratio v_2/v-1 notequalto 1 and v_2/v_1 < 1 it indicates transform factor. Hence might losses, eddy current losses we are not getting perfect transform factor From table 1.2 If we plot V_out on x-axis and number of secondary turns on y-axis we are getting a straight line passing through origin we are getting linear Relationship V proportionalto N V = aN yes, data is Ideal in 3 cases as N_2/N_1 = V_2/V_1 Relation Use of lamination core of for reducing eddy current losses, high relative (mu_t) mutual for reducing leakage of there and after reducing losses and also high resistivity for reducing eddy current can be used as core
