A coupled set of equations, one describing the time evolution of the ordinary-mode wave energy and the other describing the time evolution of the electron distribution function, is presented. The wave damping is mainly determined by T/sub X/, while the radiative equilibrium is mainly an equipartition with T/sub perpendicular/. The time rate of change of T/sub perpendicular/, T/sub X/, particle density (N/sub 0/), and current density (J/sub X/) are examined for finite-k/sub X/ electron-cyclotron-resonance heating of plasmas. The effects of collisional broadening and collisional damping are also examined. For blackbody absorbing conditions it is shown that the increase of T/sub perpendicular/ with time in electron-cyclotron-resonance heating is exponential and not linear. From the quasilinear theory it is found that the Ohkawa steady-state current drive efficiency criterion is really a consequence of the conservation laws of energy, momentum, particle density, and the collisional relaxation of the current density.
