Concept:
Resistance opposes the flow of current, while conductance represents the ease with which current flows.
Step 1: If resistance is \(R\), then conductance is:
\[
G=\frac{1}{R}
\]
Step 2: The unit of conductance is siemens.
Step 3: Reactance and impedance are used mainly in AC circuits, while susceptance is reciprocal of reactance.
Therefore, the reciprocal of resistance is:
\[
\boxed{\text{Conductance}}
\]
