Unit pA
Name picoampere
Category Electric Current
Details A petaampere (PA) is a unit of electric current in the International System of Units (SI). It represents one quadrillion (10^15) amperes. An ampere, often shortened to "amp," is the base unit of electric current, which measures the flow of electric charge through a conductor.

In practical terms, petaamperes represent extremely high currents, which are not commonly involved in everyday applications. It is more likely to be used in scientific or hypothetical discussions, such as modeling extreme astrophysical phenomena or conducting large-scale simulations.
