The problem of the current-driven linear instability of a general force-free equilibrium has been formulated in terms of a variational problem with the vector potential as the trial function. The formalism allows A·B0 ≠ 0 so that nonideal effects are modeled. The variational problem has been studied numerically for both infinite aspect ratio and finite aspect ratio tokamaks. Results of these numerical studies are presented.
