The farad (F\text{F}F) is the SI derived unit of electrical capacitance, CCC, which can be defined by the relationship C=QV\displaystyle C = \frac{Q}{V}C=VQ.
Which of the following represents the farad expressed in SI base units?
A2 s3 kg−1 m−2\text{A}^2 \text{ s}^3 \text{ kg}^{-1} \text{ m}^{-2}A2 s3 kg−1 m−2
A s4 kg−1 m−2\text{A} \text{ s}^4 \text{ kg}^{-1} \text{ m}^{-2}A s4 kg−1 m−2
A2 s4 kg−1 m−2\text{A}^2 \text{ s}^4 \text{ kg}^{-1} \text{ m}^{-2}A2 s4 kg−1 m−2
kg m2 s−4 A−2\text{kg} \text{ m}^2 \text{ s}^{-4} \text{ A}^{-2}kg m2 s−4 A−2
