Unit of conductance and impedance is Siemens [S]

Question

BlackTom AI · Accepted Answer

The statement presented is about the units used for two electrical properties: conductance and impedance.
Option a: 'True'. This would be tempting if someone thought both properties shared the same SI unit. However, conductance is measured in siemens (S), while impedance is measured in ohms (Ω). Since impedance and conductance are not measured in the same unit, declaring the unit to be Siemens for both is inaccurate. This option misleads by conflating two distinct quantities.
Option b: 'False'. This is the accurate assessment because impedance is not expressed in siemens; impedance is expressed in ohms. Moreover, impedance is a complex quantity whose magnitude has units of ohms, while conductance, the reciprocal of resistance, has units of siemens. The key conceptual distinction is that conductance and impedance are inverse concepts in different domains (one relates to ease of current flow, the other to opposition to alternating current) and their units reflect that.
Option c: 'I can't say'. This would be inappropriate here since the relevant definitions and units are well established in basic circuit theory. The question does not require ambiguous interpretation; the units are standard and widely agreed upon, so a definitive statement can be made.
In summary, the given statement mixes the unit for two different electrical properties, which leads to an incorrect claim about impedance, while correctly identifying conductance's unit. The other options either rely on a false equivalence or on unnecessary ambiguity.
