<prompt> Yakha inguqulo eyinkimbinkimbi yalesi sigwebo I-potentiometer iyithuluzi lokulinganisa amandla noma i-voltage esifundeni.  <response>: Yiqiniso, inguqulo eyinkimbinkimbi yomusho ithi I-potentiometer iyithuluzi lokulinganisa amandla noma i-voltage esifundeni esithinta ingxenye ye-voltage eyaziwayo kusuka ocingweni lwe-resistive slide bese uyiqhathanisa ne-voltage engaziwa ngokusebenzisa i-galvanometer.
