pA
picoampere
Electric currentexact by definition
The picoampere is 10⁻¹² of an ampere. It is the scale of photodiode dark current, of MOSFET gate leakage, and of the single ion channel currents that patch-clamp electrophysiology measures across a cell membrane. The factor is exact, being an SI prefix.
