1) During a 68-ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 6.9-mA current in a nearby secondary coil. The secondary coil is part of a circuit in which the resistance is 12 ?. The mutual inductance between the two coils is 3.2 mH. What is the change in the primary current?

?Ip = ______________ (A - T -Wb - V)

2) A series RCL circuit includes a resistance of 291 ?, an inductive reactance of 685 ?, and a capacitive reactance of 409 ?. The current in the circuit is 0.211 A. What is the voltage of the generator?

_______V
