Short Circuit

Electricity is very dangerous in case of surge, would be very dangerous and easy to make a fire, we often see the house, shop, warehouse also markets, malls and other burnt due to power surge. So never assume trivial to the flow of electricity that was around your room. Many people think it does not really matter which finally regret because it was too late keeping.

 How electrical short circuit could occur?

We know the electricity has to go through a closed circuit to flow. But sometimes, the power can be interrupted.Let's try this experiment to find out what is the short circuit and what's effect may occur due to a short circuit.

 
What do You Need?
1. Two wires 30 cm
2. Small lamp bulb and socket
3. 9 volt battery
4. buttons battery

 Try These:
Peel the plastic cable at both ends of the cable and at the center of the cable. 
Connect each cable on each of the batteries and connect the lamp socket. Notice what happens?
DANGER! do it carefully,Now quick connect cable chipped the middle. Do this only for two seconds, and make sure your hands 'TOUCHING THE PLASTIC CABLE'. The cable may be hot. What happened with the lamp?

Facts About Short Circuit:
When you make a regular circuit, electricity heats a wire filament for the lamp bulb and make it up. But when you crossed (the cable that connects the center had been peeled off), the light turns off. Remember: Electricity will take the path easier (shorter) of a circuit.
When you crossed, you create a short circuit. Short circuit is not going to heat the filament the lamp bulb that lights up, but it will heat up the wires. You may be burning smell when this happens.

Short circuit is very dangerous and can cause great damage. So always be alert to the eyes and nose to see and smell if there are signs of a short circuit.

The Harmful Of Alcoholic Beverages

Alcoholic beverages are drinks containing ethanol. Ethanol is a psychoactive substance and consumption led to a decrease in consciousness
Alcoholic beverages can indeed good for health, for example, warm up in the cold air. But a lot happens to excess alcohol consumption to the benefit is lost. No matter how old a person, alcohol can cause serious impact on health and himself.

Because that is in the minds of people are just alcohol and stop thinking about other things.

Kind Of Energy

Everything that we do every day requires energy as an example when we are walking,  the body's muscles convert chemical energy that we get from food which we eat , to muscles energy used for walking. Actually what energy is ? as simple we can define energy as an abilities to do work . there are kind of energy that we found in our daily life for example :


a. Chemical Energy 
chemical energy is the energy which saved in the chemical compound such as  food and gasoline.

 b. Electrical Energy
 Television and air conditioner and all other electronika tool is example tool that using electrical energy .

 c. Potential Energy 
Potential energy is energy that have in an object because of its position to other object.
there is two kind of potential energy , that are :
1.) Potential Gravitational Energy is energy that having in an object because of gravitational. for example is a water fall that falling from certain height .

2.) Potential Spring Energy is energy that having in an object because of spring force.
for example is dinamometer

d. Kinetic Energy
kinetic energy is energy which related with motion . Every moving object which contain of mass having kinetic energy .

e. Mechanical Enegy
Mechanical energy is energy which having in object because its position and its movement . Mechanical energy is an addition of potential energy and kinetic energy .

Mungkin maksud Anda adalah: beda antara dari definisi kita tahu bahwa kinerja adalah hasil kali antara gaya dan perpindahan sedangkan energi adalah
