We investigate transresistance effects in electron-hole double-layer systems with a superfluid electron-hole condensate. Our theory is based on the use of a minimum dissipation premise to fix the current carried by the condensate. We find that the drag resistance jumps discontinuously at the condensation temperature and diverges as the temperature approaches zero.
