What is Charging by Conduction?
- ITis a basic method used for transferring electric charge from one body to another by making a physical connection between two bodies
- it happens when an object having a positive or negative electric charge makes a connection with the neutral or opposite-charged body.
- Their contact causes the transferring of charge to the neutral object and charges on both objects are equal
Materials for Charging by Conduction
- charge by conduction need two materials having different electrical charges, conductors, and sources of electric energy.
- The conductor is a material that helps the current to flow easily. The commonly used conductors are metals like copper and aluminum. Insulators like rubber, plastic, and glass do not conduct current to flow and are not used for conduction charging.
Charging by Conduction Advantages
- There are several advantages provided by the conduction charge. First of all, it is a simple and basic process that needs less instruments.
- Charging by conduction is a high-speed process that just takes some seconds to completion
- It is an effective method to charge electronic devices since it allows the transfer of charges in very less time
Disadvantages of Charging by Conduction
- As it provides different advantages with that also have some drawback.
- It needs direction contacts between two bodies that can restrict it use in different applications
- Charging by conduction is hazard process if there are no proper measures taken for safety purposes.
- It can cause to damage the electronic devices if the charging process is not accurately performed
How Conduction Charging is Used in Everyday Life?
- conduction charging is very commonly used in different operations in our practical life such as phones, laptops, and tablets.
- During charging the devices plugin it into a charger that transfers charge from the power source to the devices through a cable connected
- Electric cars are also charged through the use of a conduction charging process
What is an Example of Charging by Conduction?
- A common example of charging by conduction is the use of wire to transfer the current from one point to another. The best example is mobile charging by connecting it to a charger with the use of a cable.
- That lightning is also an example of charging by conduction. When thunderstorms occur negatively charged clouds and positively charged ground make contact with each other that causes the transfer of electric charge through the air and we see a flash of light in the sky
Law of Conservation of Charge
- The law of conservation of charge is the basic law of physics that defines that the total electric charge in a closed system is constant. It means that electric charge is not created or not destroyed but can be transferred from one body to another
- This law is significant for understanding the electrical system. It helps to define electric charges that can be accumulated on the body surface and also define how current flows in conductors
- It’s used for the design and use of electrical systems like power grids and other related electronic projects and devices.It is also helpful for scientific research like the study of subatomic particles and behaviors of electromagnetic waves
How to Charge by Conduction
- Charing through conduction is a basic process that needs a direct connection between two bodies with different charges. For charging the objects through conduction some steps involved are discussed here
- Make sure that the electrical energy source is off to avoid any accidents
- Then know about the two objects one has a negative or positive charge and the other is neutral or oppositely charged
- Then make a connection to the object with a neutral or opposite-charged body
- The electric charges will transfer from charged body to another opposite-charged or neutral body and both bodies have equal charges
Charging by Conduction Using a Positively Charged Object
- It is a process in which objects are charged by transferring positive charges from charged body to the neutral body. In this process positively charged body came close to the neutral body then charges flow to neutral objects then bot objects have equal charges
- An example of this process is glass rubbing with silk, When a glass rod is rubbed with silk rod gets positively charged and the silk becomes get negatively charged
- If a positively charged glass rod is close to a neutral body like doorknob positive charges on the glass will go to the glass rod that is in contact with metal and get a positive charge. This process can be done with non-metals like plastic and rubbers
- Another example of charging by conduction is the use of positive objects is charing metallic spheres with the use of the Van de Graaff generator.
- Van de Graaff generator. is a device that used a belt for the creation of static electrical energy. When the belt moves it charged the metallic sphere at the upper side of the generator,
- The sphere gets positively charged and charges can be transferred o other bodies through conduction.
Charging by Conduction Using a Negatively Charged Object
- In this process, objects get charged by transferring negative charges to neutral objects. For this negatively charged body to come close to the connection with neutral bodies that causes negative charges to flow from charged body to neutral objects and get equilibrium
- An example of this process is the use of negatively charged objects to rub a plastic comb with wool. When the comb is rued with wool, the comb gets negatively charged and the wool becomes positively charged.
- If a negatively charged comb came close to neutral metallic bodies like doorknob negative charges on the comb flow to metallic objects to get a negative charge
Safety Considerations when Charging by Conduction
- During conduction charging it is necessary to follow some safety measures for safe charge transfer. First of all, ensure that the source of energy is off before starting the charging process
- Another is avoid to touching the live wires or objects that is contact with a live wire.
- Try to use accurate devices like rubber gloves and safety glasses and make protection from electric shock
Comparison of Charging by Conduction with Other Charging Methods
Charging Method Advantages Disadvantages Examples Conduction it is a fast operation Fast, effective, direct contact it needs direct contact Phone charging with a wire Induction There is no No direct contact, convenient process It is slower and less efficient Phone charging with the use of a wireless charging pad Static It can charge different objects without the use of a direct connection It is a very slow process and limited range There is Static electricity generated by rubbing a balloon on your hair
Future of Charging by Conduction
- This process has been used for many previous years and is continuing to use in the future. Though with the advancement in technologies new and more effective methods of charging are introduced making charging by conduction obsolete.
A quick and easy way to charge electrical gadgets is through conduction, which involves passing electricity directly from one item to another. It is present in numerous commonplace gadgets, like computers, tablets, and cell phones. Conduction charging provides different advantages like high-speed operations and simple processes but also has some disadvantages that need a physical connection between two objects As technology develops, it’s probable that other, more effective charging techniques may be created, rendering charging via conduction obsolete.
What is the Difference Between Charging by Induction and Charging by Conduction?
Charging by conduction explains electric charge transfer from one object to another by making direct contact while charging by induction uses magnetic fields for energy transfer.
Is Charging by Conduction Safe?
Charing by conduction can be a safe process if proper precautions are taken like off the energy source and avoid to touch live wires.
Can We Use any Material for Charging by Conduction?
No, only conductive materials can be used for charging by conduction.
Can charge by conduction damage electronic devices?
Yes, if the charging process is not accurately performed the devices can be damaged.
Is charging by conduction the effective method of charging electronic devices?
No, Some other methods like charging by induction and charging by electrostatic induction are more effective techniques.
