Resistance ($R$) leads to ohmic voltage drops and energy loss ($I^2R$).

Inductance ($L$) leads to inductive reactive voltage drop ($I \cdot j\omega L$).

Capacitance ($C$) induces the Ferranti effect, potentially increasing the receiving end voltage at light loads.

A ring main is essentially a closed loop, making it more stable than a radial system.

Provides higher reliability through redundant supply paths.

Offers better voltage regulation compared to radial feeders.

Increased complexity in fault current analysis and protection coordination.

Higher initial cost due to additional conductor material requirements.

Urban power distribution systems.

Industrial plant power grids.

In short lines, capacitance is often ignored (short line approximation), but for accurate AC ring layout calculations, all parameters must be considered.

Option A, C, and D are incorrect because they only account for individual components, neglecting the overall complex impedance and admittance matrix of the transmission link.
