During a 74-ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 6.6-mA current in anearby secondary coil. The secondary coil is part of a circuit in which the resistance is12 Q. The mutual inductance between the two coils is 3.2 mH. What is the change in the primary current?Alp=
