Unit EF
Name exafarad
Category Capacitance
Details An exafarad (EF) is a unit of measurement for capacitance in the field of electrical engineering. Capacitance is the ability of a physical body or system to store electrical energy in the form of an electric charge. The standard unit of capacitance is the farad (F), named after the British scientist Michael Faraday.

An exafarad is equal to 10^18 farads or one quintillion (1,000,000,000,000,000,000) farads. This is an extremely large unit of capacitance and is rarely used in practical electrical measurements because such huge capacitance values are not typically encountered in real-world applications. Instead, capacitance is generally measured in smaller units such as microfarads (µF), nanofarads (nF), or picofarads (pF).
