From kinetic Vlasov equation for collisional plasmas distribution function insquare-law approximation on sizes of intensivities of electric fields isreceived. The known integral of collisions of relaxation type, so-called BGK(Bhatnagar, Gross, Krook) integral of collisions is considered. The formula forcalculation electric current at any temperature (any degree of degeneration ofelectronic gas) is deduced. This formula contains an one-dimensionalquadrature. It is shown, that the nonlinearity account leads to occurrence thelongitudinal electric current directed along a wave vector. This longitudinalcurrent is orthogonal to a known transversal classical current, received at thelinear analysis. When frequency of collisions tends to the zero, all receivedresults for collisional plasmas pass in corresponding formulas forcollisionless plasmas. The case of small values of wave number is considered.It is shown, that the received quantity of longitudinal current at aspirationof frequency of collisions to zero also passes in corresponding expression ofcurrent for collisionless plasmas. Graphic comparison of dimensionless quantityof current depending on wave number, frequency of oscillations ofelectromagnetic field and frequencies of electron collisions with plasmaparticles is carry out.
