Unit YA
Name yottaampere
Category Electric Current
Details A yoctoampere (yA) is a unit used to measure electric current. It is an extremely small unit, being one of the smallest units possible in the decimal system.

The term "yocto" is a metric prefix that represents 10^(-24). Therefore, one yoctoampere (yA) is equal to one septillionth (10^(-24)) of an ampere (A), the standard unit of electric current in the International System of Units (SI). In other words, 1 yA = 1 x 10^(-24) A.

The yoctoampere is typically used in fields like nanotechnology, quantum physics, or in applications dealing with very small currents, where precise and sensitive measurements of extremely low levels of electric current are necessary.
