For the symmetrical iron core shown in Fig. 122, two coils wound. When coil 1 is connected to the AC network, the voltage at the terminals of coil 2 V2 = 13.2 V. When coil 2 is connected to the same network, the voltage at the terminals of coil 1 V1 = 120 V. What is the ratio of the numbers of turns of the coils? Assume that the magnetic flux created by each coil does not leave the core.
