Everything in this world harms us if we don’t know how to use or handle it. Electricity is very important and useful one, if we don’t have electricity, we can’t operate computers, big machines, lights and other equipment using electricity. But on the other hand electricity can be a harmful one, if you don’t know how to it, it could be your end.
So, properly handling and use is recommended to avoid any harmful effects. Electricity can flow to the materials called conductor.
What is conductor?
Conductor – is a material with plenty of free electrons, voltage or current can flow.
Example: iron, metal, nickel, silver, gold, aluminum, germanium, tungsten, nicrome, water, copper
Silver
• is the best conductor.
• very low resistance.
SCAIL – is the descending order of conductivity of a conductor used in an electronic circuit.
• S – Silver
• C – Copper
• A – Aluminum
• I – Iron
• L – Lead
Now you know the materials that conduct electricity, so you are now aware about it. If you can see any conductor materials with the presence of electricity don’t touch it without using insulator.
If we have conductor, we also have insulator.
I have a simple question, why birds can land to a power-line with 1000 volts presence without electrifying happens? A good question needs a good answer, because bird’s foot has an insulator.
What is insulator?
Non Conductor or Insulator – is a material lacks or no free-electrons, voltage or current cannot flow.
Example: rubber, plastic, paper, glass, cork, wood, cloth, porcelain
Glass
• is the best insulator at room temperature
• it cools
Insulator can be use in troubleshooting deals with electricity. It is safe to handle electricity when you are using insulator, rubber is a common insulator use in all aspect of dealing with electricity.
