problem 1: Describe the construction and working principle of Transformer?

problem 2: Derive an emf equation of a single phase transformer. The maximum flux density in the core of 250/3000 volts, 50 Hz single phase transformer is 1.2 Weber per square meter. If the emf per turn is 8 volts, then find out the primary and secondary turns and area of the core.

problem 3: The primary winding of a 50 Hz single phase transformer has 480 turns and fed from 6400 v supply. The secondary winding has 20 turns. Find out the peak value of flux in the core and the secondary voltage.

problem 4: What are the various functions of a transformer?

problem 5: Derive an expression for the voltage per turn of a transformer.

problem 6: What are the different losses taking place in a transformer on load? How can such losses be found out experimentally?

problem 7: Define the term voltage regulation of a transformer. Deduce the expression for the voltage regulation.

problem 8: The number of turns on the primary and secondary windings of a single phase transformer is 350 and 35 correspondingly. If the primary is connected to a 2.2 kV, 50 Hz supply, and then find out the secondary voltage.
