MGVCL Exam Paper (30-07-2021 Shift 2) Which one of the following statement is TRUE? The current carrying capacity of cables in DC is less than that in AC. In the cables, sheaths are used to provide enough strength. Underground cables are laid at sufficient depth to avoid being unearthed easily due to removal of soil. In the cables, the location of fault is usually found out by comparing the capacitances of insulated conductors. The current carrying capacity of cables in DC is less than that in AC.
