10kva single transformer has turns ratio of 300 / 23.

1. An ideal transformer with a 450 turn primary connected to a 600 V, 60 Hz supply line needs to output 240 V from the secondary. A 100 load is connected across the secondary. How many turns the secondary must have to output the desired voltage? What is the current through the load? What is the current drawn through the primary?

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.

A 30 KVA transformer has 300 turns on the primary and 50 turns on the secondary winding. The primary is connected to 1500 V, 50 Hz supply. Find the full load primary and secondary current the secondary emf maximum flux in the core
