We consider adiabatic pumping of electrons through a quantum dot. There are two ways to operate the pump: to create a de current (I) over bar or to create a dc voltage (V) over bar. We demonstrate that, for very slow pumping, (I) over bar and (V) over bar are not simply related via the dc conductance G as (I) over bar = (V) over barG. For the case of a chaotic quantum dot, we consider the statistical distribution of (V) over barG-(I) over bar. Results are presented for the limiting cases of a dot with single-channel and with multichannel point contacts.
