A single-phase, 50 Hz transformer has 25 primary turns and 300 secondary turns. The cross-sectional area of the core is 300 cm2. When the primary winding is connected to a 250V supply, determine (a) the maximum value of the flux density in the core, and (b) the voltage induced in the secondary winding.
