Because a short allows/causes very large current flow, which "overloads" the wire [conductor]. When a conductor [wire] carries much more current than is safely capable, then the conductor heats up, and can cause enough heat to ignite the insulation and adjacent combustible materials on fire.
What else can I help you with?
What are the hazards of ammeter?
it will explode if it short circuits
What is the name of the circuit that is neither parallel nor series?
FEEDBACK CIRCUITS. In addition to parallel and series circuits, there are also closed and short circuits.
Why is low voltage circuits separated from higher voltages?
avoid crosstalksafety, a short between them could cause hazardous voltages where none are expectedprotect low voltage equipment from damageetc.
What a short hand way of drawing electrical circuits?
electrical symbol
In the simplest of dc circuits where the resistance is zero what kind of circuit is it?
A short circuit.
Is there any fire caused by floods in places where electricity is used?
Although floods can cause short circuits, they also tend to put out fires. Flooding has not been associated with fire.
Why must short circuits be opened instantly?
Short circuits cause extreme amounts of electrical and mechanical stresses on equipment. Equipment that will regularly carry 100amps of current can be exposed to thousands of amps of current. transformers explode, lines vaporize, poles start on fire, etc. if short circuits are not removed as soon as practical.
What are the causes of fire in electrical circuits?
Overloading the circuit or a device like a power strip will cause the wiring to heat up at it's weakest point and can result in fire, it can also cause insulation to melt resulting in an electrical short.
Why are fuses and curcuit breakers used in household circuits?
Fuses and circuit breakers are used to protect the wiring and devices from overload and heating caused by short circuits, short circuits that, if unprotected, could cause major damage and/or fire due to excessive current.
What causes a short circuits?
-circuit damage -overheating -fire or explosion causes a short circuit.
Can an insect cause an electrical short circit?
Yes, some insects can cause electrical short circuits. The insects can make nests inside fuse boxes and this can cause malfunctions.
What would cause a fuse to blow when you turn the lights on your 1988 300zx?
A short circuit. Look through your connections to your 'lights' and make sure there are no short circuits. If you want to know about short circuits see related links below.
When was Short Circuits - film - created?
Short Circuits - film - was created in 2007.
What would cause both the turn signal and brake light fuses to blow on a 2001 Ford Escape?
short circuits in the turn signal and brake light circuits
Why is a short circuit considered a safety hazard?
A spark from a short circuit can cause a fire .
What are two devices that prevent short circuits?
Insulation in good condition and keeping equipment enclosures on and tight are two things to prevent short circuits. Fuses and breakers do not prevent short circuits. They eliminate damage that could be caused by short circuits.
What can cause a circuit breaker to trip?
A circuit breaker can trip due to overloading, short circuits, or ground faults.
