The correct answer is C. Farad.
A farad (F) is the unit of capacitance in the International System of Units (SI). It is named after Michael Faraday, an English physicist and chemist who is considered one of the most influential scientists of all time.
Capacitance is the ability of a body to store an electric charge. It is measured in farads, which are defined as the charge required to produce a potential difference of one volt across the capacitor.
The farad is a large unit of capacitance, so smaller units are often used in practice. The microfarad (μF) is one millionth of a farad, and the picofarad (pF) is one trillionth of a farad.
Capacitors are used in a wide variety of electronic devices, including computers, cell phones, and televisions. They are also used in power supplies and filters.
The other options are incorrect.
- Henry (H) is the unit of inductance.
- Ohm (Ω) is the unit of resistance.
- Farad/m is the unit of permittivity.
