About Picoamperes
The picoampere (pA) equals 10⁻¹² A, the standard scale for electrometer measurements, reverse-bias diode leakage, and single ion-channel currents in patch-clamp electrophysiology. A typical open potassium channel carries 1-20 pA; high-quality electrometer inputs resolve below 1 pA; insulation resistance measurements on cables are reported in pA at known voltage. 1 pA = 10⁻³ nA = 10³ fA.
About Attoamperes
The attoampere (aA) equals 10⁻¹⁸ A, the scale of single-electron tunnelling currents in quantum devices. Individual electrons tunnelling through a molecular junction or quantum dot produce average currents of order 1-100 aA when measured at sub-microsecond resolution; cryogenic shot-noise electrometers achieve sub-attoampere sensitivity. 1 aA = 10⁻³ fA = 10⁻¹⁸ A.
