Subsection 4.3.4 Delta Circuit
In a delta configuration, three components are connected in a closed loop resembling a triangle. Each component is connected across two lines, and no neutral point is used.
In a three-phase delta circuit,
\begin{align}
V_L \amp= V_\phi.\tag{4.3.4}\\
I_L \amp = \sqrt{3} I_\phi\tag{4.3.5}
\end{align}
