Conductance is the reciprocal of?

The correct option is A

Resistance

Conductance:

1. Conductance may be computed by first finding the resistance(R) using Ohm's law and would then calculate the reciprocal of it.
2. The alphabet "G" represents conductance.
3. The unit of conductance is the $\mathrm{siemens}\left(\mathrm{S}\right)$.
4. Formula: $\mathrm{G}=\frac{1}{\mathrm{R}}$

Therefore, conductance is the reciprocal of resistance. Hence option A is correct
