What are the dangers of short circuit and overload?

The dangers of short circuit are it can cause fires which can damage things and will even caused lives. It can cause so much trouble to the family and community. It will destroy appliances in the house and will ruin properties because of the fire it caused.We should really try our best to avoid short circuit and overload by maintainig our appliances at constant state and provide it a better care so that in the end we will not suffer the consequences of it.rest of the network and potentially causes circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protector.

Here are some pictures showing the dangers of short circuit and overload:

So PEOPLE!!! THE Safety lies on US!!! let US follow the Safety PRECAUTIONS!!!

Why will too many electrical devices operating at one time often blow a fuse?

Too many electrical devices operating at one time often blow a fuse because too much current flow can lead to excessive heating of the wire. Fuses have the essential component which is a metal wire or strip that melts when too much current flows. For this reason, a fuse will blow out if too much current flows through it. Fuses blow quickly for massive overloads, like AC shorts to a grounded chassis. They blow with a some time lag - maybe only a second or two, up to minutes, as the overcurrent gets closer to the fuse's actual rating. Anything that uses enough power to cause the AC line current to exceed the rating of the fuse will eventually cause it to blow. It is important to remember that a fuse NEVER blows without something else being wrong. It could be that: fuse is the wrong rating - replace it with the correct rating power tube shorted rectifier tube shorted power supply filter cap failing Carbon trails on the output tube sockets between the plate lug and the other electrodes, especially the heater electrodes. power tubes have lost bias or biased incorrectly power section of the amp is oscillating at too high a frequency to hear there is an ac wiring short or high leakage power transformer is faulty choke (if present) is shorted/leaking to chassis

When is there an overload in a circuit?

Overload happens in a situation where the wiring to or within a machine or system is subjected to a greater electric current load than it was designed to carry, leading to excessive heating of the wires and a possibility of fire. This excessive current load can be a result of electrical insulation failure ( a short circuit) or human error. A correctly designed electrical system incorporates suitable overload protection devices to prevent damage should such a situation occur. Fuses and circuit breakers are most commonly employed for this purpose.

Here are some pictures about overload and its cause:

3. How do Circuit breakers Work?

The circuit breaker- is an absolutely essential device in the modern world, and one of the most important safety mechanisms in your home. Whenever electrical wiring in a building has too much current flowing through it, these simple machines cut the power until somebody can fix the problem. Without circuit breakers (or the alternative, fuses), household electricity would be impractical because of the potential for fires and other mayhem resulting from simple wiring problems and equipment failures.

Circuit breakers are designed to trip (fuses in your fuse box are designed to blow) and turn off power when any of the following dangerous situations occur:

A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

2. What is a fuse? What happens when you blow a fuse?

Fuse is a type of overcurrent protection device. Its essential component is a metal wire or strip that melts when too much current flows.When the fuse element blows, the indicating pin extends to activate the micro switch or relay which in turn triggers an event.

1. What is short circuit? What is the common cause of unintentional short circuits in electrical devices? ___---- A short circuit (sometimes abbreviated to short or s/c) allows a charge to flow along a different path from the one intended. The electrical opposite of a short circuit is an open circuit, which is infinite resistance between two nodes. It is common to misuse "short circuit" to describe any electrical malfunction, regardless of the actual problem. ___----A short circuit is an accidental low-resistance connection between two nodes of an electrical circuit that are meant to be at different voltages. This results in an excessive electric current limited only by the Thevenin equivalent resistance of the rest of the network and potentially causes circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. ___----In circuit analysis, the term short circuit is used by analogy to designate a zero-impedance connection between two nodes. This forces the two nodes to be at the same voltage. In an ideal short circuit, this means there is no resistance and no voltage drop across the short. In simple circuit analysis, wires are considered to be shorts. In real circuits, the result is a connection of nearly zero impedance, and almost no resistance. In such a case, the current drawn is limited by the rest of the circuit. ___----The Short Circuit is a more serious reason for a breaker tripping. A short is caused when the hot wire (black) touches another hot wire or touches a neutral wire (white). It can also be caused if there is a break in a wire in the circuit. Shorts are a bit more difficult to diagnose because they can be caused by the wiring in your home or in something you have plugged into an outlet. We have here the sample picture:

THINKING BACKto the time when we first beganto be friends, I wonder-WHAT IF the different roadswe traveled before we methad never come together?WHAT IS we hadn't hadso much in common?WHAT IF we hadn'tfelt close to each otherright from the startand grown closer astime went by?LUCKILY,everything happened just right.And I'm so glad,because our friendshipmeans a lot to me.And I know it always will.

oh!! fEeLinGs!!!!!

What Is It That I Love?If asked why I love her I would sayIt’s the sway in her hips,the thickness in her thighs.It’s the lust in her lips,the love in her eyes.It’s the softness of her skin,the silk in her hair.It’s the twist in her walk;it’s the sweetness in her talk.It’s the way she loves methat makes me love her each day.That is what I would say....

The Magic Of Love!!!!! Love is like magicAnd it always will be.For love still remainsLife's sweet mystery!!Love works in waysThat are wondrous and strangeAnd there's nothing in lifeThat love cannot change!!Love can transformThe most commonplaceInto beauty and splendorAnd sweetness and grace.Love is unselfish,Understanding and kind,For it sees with its heartAnd not with its mind!!Love is the answerThat everyone seeks...Love is the language,That every heart speaks.Love can't be bought,It is priceless and free,Love, like pure magic,Is life's sweet mystery!!

Love feels no burden,thinks nothing of trouble,attempts what is above its strength,pleads no excuse of impossibility...It is therefore able to undertake all things,and it completes many things,and warrants them to take effect,where he who does not love would faint and lie down.Love is watchful and sleeping, slumbereth not.Though weary, it is not tired;though pressed, it is not straitened;though alarmed, it is not confounded...

A friend is someone we turn towhen our spirits need a lift.A friend is someone we treasurefor our friendship is a gift.A friend is someone who fills our liveswith beauty, joy, and grace.And makes the whole world we live ina better and happier place.

You are friendly, kind and caringSensitive, loyal and understandingHumorous, fun, secure and trueAlways there... yes that's you.Special, accepting, exciting and wiseTruthful and helpful, with honest blue eyesConfiding, forgiving, cheerful and brightYes that's you... not one bit of spite.You're one of a kind, different from othersGenerous, charming, but not one that smothersOptimistic, thoughtful, happy and gameBut not just another... in the long chain.Appreciative, warm and precious like goldOur friendship won't tarnish or ever grow oldYou'll always be there, I know that is trueI'll always be here... always for you!!!

Friendship is like the breeze,You can't hold it,Smell it,Taste it,Or know when it's coming,But you can always feel it,And you'll always know it's there,It may come and then go,But you can know it'll always be back.

i think this ends my feelings!!!! tHanK yOu 4 rEadiNg!!!!!mwaah!!!
