If two coils placed next to one another have a mutual inductance of 4.94 mH, what voltage is induced in one when the 2.00 A current in the other is switched off in 31.2 ms

** urgent** the voltage across the primary winding is 350,000 v, and the voltage across the secondary winding is 17,500 v. if the secondary winding has 600 coils, how many coils are in the primary winding? a- 30 coilsb- 583 coilsc- 12,000 coilsd- 332,500 coils
