Definition. One farad is defined as the capacitance across which, when charged with one coulomb, there is a potential difference of one volt. Equally, one farad can be described as the capacitance which stores a one-coulomb charge across a potential difference of one volt.

How big is a 1 Farad capacitor?

A 1-farad capacitor would typically be pretty big. It might be as big as a can of tuna or a 1-liter soda bottle, depending on the voltage it can handle. For this reason, capacitors are typically measured in microfarads (millionths of a farad).

Is 1F capacitor possible?

1-farad capacitance is not possible because it requires a sphere of the radius in thousand of meters to store charge, which is practically not possible.
