15.6 Exercise 24

Avg difficulty 2.5

The 335-kV ac electricity from a power transmission line is fed into the primary winding of a transformer. The ratio of the number of turns in the secondary winding to the number in the primary winding is Ns/Np=1000N_{\text{s}} / N_{\text{p}} = 1000. (a) What voltage is induced in the secondary winding? (b) What is unreasonable about this result? (c) Which assumption or premise is responsible?
