What is the unit of electrical capacitance?

Answer

Farad

The story behind the answer

Farad (F) is the SI unit of electrical capacitance, which measures how much electric charge (Q) a device can store per volt (V) of potential: C = Q/V, so 1 farad = 1 coulomb per volt. It’s named after Michael Faraday, a pioneer of electromagnetism and the science behind capacitors and Faraday cages.

To remember: “Capacitance stores Charge per Volt—F for Farad, F for Faraday.” The other options are different units: henry (H) for inductance, watt (W) for power, and gauss (G) for magnetic field strength in the cgs system (tesla in SI). Capacitors with higher farads can hold more charge at the same voltage,
