here [U.sub.0], [I.sub.0], [U.sub.[infinity]] is the initial voltage and current and the steady state voltage of the disconnected generator; [U'.sub.0], [U".sub.0] is the initial values of transient and sub transient voltages; [T.sub.'d0], [T".sub.d0] is the direct axis open circuit transient and sub transient time constants; [x.sub.d], [x'.sub.d], [x".sub.d] is the direct axis synchronous, transient and subtransient inductive reactance's.
This can be described by a variation in the electrical impedance of the coil, that is, its ohmic resistance and inductive reactance.
The inductive reactance of Coax is calculated via the equation below [3]:

velocity does not give a straight line, however, due to the fact that the armature of the generator possesses capacitive and inductive reactance. Given the importance of electromagnetic induction in physics and technology this is a highly appropriate experiment for the introductory physics course.
The formula [X.sub.L] = 2[pi]fL provides the expression for inductive reactance, but here f is the knee frequency which is defined as 0.5/Tr, Tr = rise time.
Because such a structure will be inherently inductive there will be some inductive reactance opposing current flow, but it can be easily eliminated by adding some series capacitance to form a series-resonant circuit.
which means that the load network is slightly mistuned with respect to the fundamental frequency and the values of the load network parameters should be chosen to create an inductive reactance at the fundamental frequency and capacitive reactances at the harmonic components.
Each coil has 11 turns of 0.41 mm diameter wire, and the magnitude of the impedance was measured to be 60 [omega] Since the impedance is dominated by the inductive reactance, these data yield 0.22 mH for the inductance, close to the calculated value of 0.23 mH [72].
As frequency increases, inductive reactance of straight wire increases.
Hoff made the point that the inductive reactance is affected only by the size and configuration of the channel.
