A core type transformer operates on 415 / 230 volt, 55 Hz supply. If the cross-sectional area of the core is 30 cm? and maximum flux density is 1.2 Wb/m2 , then the number of turns in primary winding will be?

A core type transformer operates on 405 / 225 volt, 55 Hz supply. If the cross-sectional area of the core is 30 cm² and maximum flux density is 1.3 Wb/m² , then the number of turns in primary winding will be A 4 pole lap wound enerator has 36 slots with 20 conductors/slot and the average emf generated in each conductor is 1.78 volts. Then the Total EMF generated in volt is

1- When 400 volts, 60HZ is applied to the transformer primary winding maximum flux in the core is--

A single-phase transformer is required to step down the voltage from 1100 V to 230 V at 50 Hz. The maximum value of the flux in the core is 0.20 Wb. Determine the number of turns in the winding on both sides.
