What happen when short circuit happen in electrical outlet and appliance

Every time you use your electrical outlet that connected to electrical appliance and it works good. But suddenly a sparks created in the electrical appliance and get burn or explode. The MCB that connected to the electrical outlet trip. So What the heck happens? Well dummies if you read my previous post (Fault in Electrical Circuit) You probably know that is short circuit. The questions is what happen when a short circuit get in electrical outlet and appliance? Lets find out.
Short circuit is an electrical circuit fault,when different current carrying conductors contact each other. Like Neutral wire contact Live. When this happen you MCB will instantly trip in order to protect your electrical appliance and rid you from getting shock.  

When you look into further, When a live wire bypass to neutral accidentally, the current will increase and the voltage will be near zero. This is because the conductor of both wire is less resistance. This is why current increase in first place. The reason why voltage becomes zero is as we know voltage is a electrical potential. When the conductors bypass another conductor, the voltage will choose the less resistance path that make the voltage zero.

Using Ohm's Law you can also see when the resistance is 0 The voltage is zero too. So the current will get higher. When short circuit occur a huge sparkles with arcs. This is dangerous to human when comes to contact with it. even contact with water is so dangerous. 

There's some benefits from short circuit that people used to do everyday like welding. Grounding the metal with ground cable and hold live wire with welding electrode. when the electrode touch the ground,it will make sparks and arc to melt the electrode and stick to the metal. 

There's also a dangerous thing about short circuit. It cause you to pass out or second degree burn on you. So stay away when short circuit happens. Short circuit even happen in DC also. Like in electronics,if the components didn't solder rightly, the component might pin will touch other component to make short circuit.


 In Overhead transmission line also can be short circuit if the distance between the cable is so closely. 

FOLKS YOU HAVE TOO BE ALWAYS AWARE OF ELECTRICAL ACCIDENTS. IT MAY HAPPEN ANYTIME. ALL YOU NEED TO DO IS MAKE YOURSELF SAFE. SAFETY FIRST.
