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 Nanoamperes

The nanoampere (nA) equals 10⁻⁹ A, typical for reverse saturation currents of silicon diodes, quiescent supply currents of CMOS logic, and microelectrode measurements in analytical electrochemistry. A silicon p-n junction at room temperature has a saturation current of 1-10 nA; a well-designed op-amp input bias current is 1-100 nA; wearable biosensors commonly operate in the nanoampere range. 1 nA = 10⁻³ µA = 10³ pA.
