Correct option is C
Dead Short:
· A
dead short occurs when there is a direct connection between the live conductor and the ground or between two points of opposite potential (e.g., phase-to-ground or phase-to-phase).
· It results in a
complete short circuit, causing a large current surge and often tripping protective devices like circuit breakers or fuses.
Partial Short:
· A
partial short happens when the short circuit is not a direct connection to the ground but instead involves a resistive path or a short circuit to another wire.
· This results in a
reduced current flow compared to a dead short, but it still causes power loss, heating, and potential equipment damage.
Key Difference:
· A
dead short is typically a direct, catastrophic event (e.g., live wire touching ground).
· A
partial short is less severe and involves partial continuity through a resistive path or unintended connection.
