Which scientist gives his name to the SI unit of capacitance, the farad?

Michael Faraday gives his name to the SI unit of capacitance, the farad.

The farad measures how much electric charge a capacitor stores per unit of potential difference: one farad equals one coulomb per volt. The unit honors Faraday because his experiments established key links between electricity, magnetism, and changing magnetic fields.

Faraday was an English scientist who discovered electromagnetic induction in 1831 and developed the first practical electric generator concepts. He also introduced important ideas about electric and magnetic fields, although he had little formal mathematical training.

A common mix-up is confusing the farad with the unit of electric charge, the coulomb, or the unit of potential difference, the volt. In practice, capacitors usually have values such as microfarads, nanofarads, or picofarads rather than whole farads.
