In Millman’s theorem, **G** represents the **conductance** of a circuit element, which is the reciprocal of its resistance. Mathematically, it is:
\[
G = \frac{1}{R}
\]
Where:
- **R** is the resistance of the element.
- **G** is the conductance, measured in siemens (S).
Millman’s theorem is used to simplify the analysis of circuits with multiple voltage sources in parallel. The formula involves the sum of the voltages divided by the sum of the conductances for all elements connected in parallel. In this context, **G** is crucial because it replaces resistance in the formula, making the calculation easier when dealing with parallel circuits.
