The steady state and qtrasi-steady processes of itafinaite- ?a?ud finite-width slteet z-pinches ?tresttrdied. The relatiot'as correspotuding to the Berut'?ett relation and Pease-Br;tgitaskii ctrr'retat ofcylindrical fiber z-pinches depend 011 a geouaaetrical fstctor in the sheet z-jcinches. Tlae finite-widtla slaeet z-pitacla is approxitaaated icy a segnaetat of it?finite-xx'idth sheet z-pincla, if it is xvideenougla, and cor'resjconds to 21 ntrtnber of' (xx"idtla/thickness) tiuaaes filoer z-piuach plastaa;ts of thediatneter fl?at equ?a1s tlae sheet tlnickraess, If flue st?eet ctrrr'erat eqtr;tls tlais nuuaa1.cer tiuaaes flue fiber'current, the Pl2lSl112l created in the slaeet z-pitaches is 218 det'se as it? the filoer' z-pinches.
