Solve the following problem:
Repeat Problem 1 for k = 0.9, Np = 300 turns, and Ns = 25 turns.
Problem 1: For the air-core transformer of Fig.
a. Find the value of Ls if the mutual inductance M is equal to 80 mH.
b. Find the induced voltages ep and es if the flux linking the primary coil changes at the rate of 0.08 Wb/s.
c. Find the induced voltages ep and es if the current ip changes at the rate of 0.3 A/ms.
