Which of the following units of electrical measurement is not equivalent to 1 Siemen?

  • A
    $\Omega^{-1}$
  • B
    $\mathrm{AV}^{-1}$
  • C
    $\mathrm{CV}^{-1} \mathrm{~s}^{-1}$
  • Correct answer
    D
    $\Omega$

Solution

$\because \quad \mathrm{V}=\mathrm{IR}$ and $\mathrm{Q}=\mathrm{It}$ Conductance $(G)=\frac{1}{R}=\frac{I}{V}=\frac{Q}{V t}$ Substituting with units, $\therefore \quad 1 \text { Siemen }=\frac{1}{\Omega}=\frac{A}{V}=\frac{C}{V s}$

Hence, the correct answer is option: 'D'.
