  We model an overdamped Brownian particle that is subject to resetting
facilitated by a ratchet potential on a spatially periodic domain. This
asymmetric potential switches on with a constant rate, but switches off again
only upon the particle's first passage to a resetting point at the minimum of
the potential. Repeating this cycle sustains a non-equilibrium steady-state, as
well as a directed steady-state current which can be harnessed to perform
useful work. We derive exact analytic expressions for the probability densities
of the free-diffusion and resetting phases, the associated currents for each
phase, and an efficiency parameter that quantifies the return in current for
given power input. These expressions allow us to fully characterise the system
and obtain experimentally relevant results such as the optimal current and
efficiency. Our results are corroborated by simulations, and have implications
for experimentally viable finite-time resetting protocols.
