The farad is a unit of electrical capacitance, named after the English physicist Michael Faraday. It measures the amount of electric charge stored in a capacitor when an electric potential difference (voltage) across it is one volt. The farad can also be defined as the capacitance between two plates that have an area of one square meter and are separated by a distance of one meter from each other. In other words, it is equal to 1 coulomb per volt or 1/1 ohm-meter2 per second4 (F/V).

The SI unit for capacitance is actually called “the Farad” which stands for “Farads” – however this term has been shortened to just ‘farads’ in everyday usage. This means that if you hear someone saying they need 100 microfarads then what they really mean is 0.0001 F or 10−6 F. To put this into perspective, most electrolytic capacitors used in electronics range up to around 1000 μF so these would be equivalent to 0.001 F or 10−3 F.

In summary, the definition of Farad can be stated simply as: A farad (abbreviated “F”) represents how much electrical charge will flow through a circuit with an applied voltage difference equal to one Volt; thus it measures electrical capacity and stores energy within itself like any normal capacitor does!

It’s important not only because we use them frequently but also because understanding their behavior helps us to better understand electricity and its applications within our daily lives!
