Proximity effect in transmission lines causes:
AUniform distribution of current density
BComplete loss of line capacitance
CNon-uniform distribution of current density across the conductor cross-section
DReduction of conductor temperature
Explanation
Proximity effect occurs when alternating currents flow through adjacent conductors, altering flux linkage. The magnetic fields distort current distribution, forcing current to concentrate on specific sides of the cross-section and increasing effective AC resistance.
