During a 63-ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 7.8-mA current in a nearby secondary coil. The secondary coil is part of a circuit in which the resistance is 12 O. The mutual inductance between the two coils is 3.2 mH. What is the change in the primary current?
