Question:

Resistors of 5 and 20Ω are connected to the primary and secondary coils of a transformer with inductances as shown in Figure 11.19. At time t = 0, with no current flowing, a voltage E = 100V is applied to the primary circuit. Show that subsequently the current in the secondary circuit is

20 -(e- 41 e-(11+41)/2 _ e-(11-41)1/2)
