Which of the following units of electrical measurement is not equivalent to 1 Siemen?
- A \(\Omega^{-1}\)
- B \(\mathrm{AV}^{-1}\)
- C \(\mathrm{CV}^{-1} \mathrm{~s}^{-1}\)
- D \(\Omega\)
Answer & Solution
Correct Answer
(D) \(\Omega\)
Step-by-step Solution
Detailed explanation
\(\because \quad \mathrm{V}=\mathrm{IR}\) and \(\mathrm{Q}=\mathrm{It}\)
Conductance \((G)=\frac{1}{R}=\frac{I}{V}=\frac{Q}{V t}\)
Substituting with units,
\(\therefore \quad 1 \text { Siemen }=\frac{1}{\Omega}=\frac{A}{V}=\frac{C}{V s}\)
Conductance \((G)=\frac{1}{R}=\frac{I}{V}=\frac{Q}{V t}\)
Substituting with units,
\(\therefore \quad 1 \text { Siemen }=\frac{1}{\Omega}=\frac{A}{V}=\frac{C}{V s}\)
