Question

Which of the following units is not equivalent to Farad?

• A. $C{V}^2$
• B. $\frac{J}{V^2}$
• C. $\frac{Q^2}{J}$
• D. $\frac{Q}{V}$

Answer 1

The correct option is A

$C{V}^2$

The explanation for the correct option:

In the case of option (A),

1. The Farad can be defined as the unit of electrical capacitance.
2. It provides a means to measure the ability of a substance to store electric charges.
3. Charge $Q$ can be written as $Q=\left(\text{Farad}\right)\times V$
4. $J$ can be written as $J=\left(\text{Farad}\right)\times V^2$
5. Farad can be written as $\frac{Q}{V}$, $\frac{Q^2}{J}$ and $\frac{J}{V^2}$.

Hence, option (A) is correct.
