What is a Dead Short ?
Dead Short Definition
A dead short is when electrical current flows where it shouldn’t, with no resistance, often causing damage or hazard.
Comparison with Short Circuit
Unlike a short circuit, which has some resistance and reduced voltage, a dead short shows zero voltage and resistance, indicating a more severe problem.
Give an example
Bolted Fault Similarity
A bolted fault, like a dead short, also exhibits zero resistance, but it specifically involves connections to ground.
Ground Fault Differences
Ground faults involve some resistance and usually occur when a live wire touches a grounded surface, unlike the zero-resistance path in a dead short.
Practical Example
Demonstrating a dead short with resistors, where shorting the terminals with zero resistance leads to a drastic increase in current, bypassing the resistors entirely.
