Write a note on uses of conductors and insulator in our daily life
Answers
Answer:
Conductor
electricity switch
Iron press transfer heat to cloths
Utensils transferred energy to milk.
Cooling coils of copper inside refrigerator and AC.
Geaser for hot water
Insulators
Winter jacket
Doors of refrigerator
Handle of iron press
Handles of utensils
Electric screw driver
Thermous flasks
Water bottle.
Conductors are elements that conduct heat quickly and also can cool things quickly such as in wire coil in the back of refrigerator. It has function to conduct the heat of refrigerator to the air around refrigerator.
There are another uses of conductors in daily life as follows:
For Cooking Equipment
Kitchen closely related with our skin’s heat if we can not stand the heat. If we are not careful, our hand will get hurt or get blister if we do not wear security tool or combination of isolator while using cooking equipment. Conductor cookware is required to deliver heat from the its source for cooking.
Cookwares are made of conductor are skillet, pan, fryer. Skillet is usually made of aluminum. Aluminum is light metal compared to other metals.
2. To Iron Clothing (Iron)
Uses of conductors in daily life – Iron is a human tool used to tidy cluttered clothing with the help of heat energy generated from the flow of electricity. The metal conductor material is placed under the iron in direct contact with the clothing. In order to be used well, the top of iron uses insulator material for the convenience of the user.

3. Soldering
Solder is a tool to connect electronics components. It is usually used in workshops or places to repair electronic appliances. Like other tools the only conductors that come into contact with the tool to be solder, the part that will be moved by our hand use the insulator.
Copper Conductor for Electric Cable Fill
Copper is a pure metal that has a high electrical conductivity that is about 57 S. Copper works on the conductor cable. Cable that uses copper is wired cable, coaxial cable, NYA, NYAF and etc.
Wired cables: high-circular electric wires surrounded by insulation.
Coaxial cable: electric cable made of fine copper. It is stronger and more flexible.
One of the reasons why copper is used as a cable fill is that besides high conductivity, it also has resistance to high temperatures and moist air than steel. Its boiling point increase reaches 25950C. The material is strong, hard, elastic and able to loose or expand.
For Grilling (baking) and Cake baking (oven)
Baking tools made of conducting materials are toaster and oven. Both use the heat from the fire to ripen the food. There is manual grill using charcoal, there is also grill using heat coming from gas (stove).
The difference with the oven is from the shape, the size of the laying of cooked materials and the type of ingredients which are cooked. The heat flow for grilling is only about at the bottom only and roasting wire is required above the heat source. The heat of the oven is distributed to all directions evenly to the food.

5. Gold
Although gold reacts chemically by free chlorine, good conductivity and general resistance to oxidation and corrosion in other environments (including resistance to nonchlorinated acids) has led to the industry being used extensively in the electronic age as a thin layer of electrical connectors of all kinds, ensuring good connection.
6. Silver
In the auto parts industry, the benefits of silver are used in the manufacture of spark plugs. Spark plugs on the vehicle play an important role in supporting the engine heating perfectly. In this case, the best spark plugs for motor vehicles are spark plugs made of silver.
Silver has a small resistance so as to produce optimal combustion on the machine. As a result, the motor vehicle will work very well. This property is also the reason for the use of silver as a cable making material.
The conductivity properties of copper wire are not as good as silver wire. Of course this is directly proportional to the price. Silver wire is worth selling higher than copper wire. Fair enough, considering the quality is also better.
Silver wire will be packed and used as cables for various electronic devices. Starting from the power cable, audio connector cable, even the cable used for high quality loudspeakers. Silver cable can be found in the best quality electronic products with a fairly high price in the market.
For example, gold used in more expensive electronic cable connectors , such as audio, video and USB cables. The advantage of using gold over other metal connectors such as tin in this app is highly debatable. Gold connectors are often criticized by audio-visual experts as unnecessary for most consumers and seen as just a marketing tactic.
