Grounding is used for dircharging In case of charging by

In summary, grounding is a method used for discharging excess charge. When a negatively charged sphere is grounded, half of the negative charge is transferred to a neutral sphere. The amount of charge transferred depends on the size of the spheres, with the Earth being able to hold a larger amount due to its size. In comparison to charging by conduction, charging by induction results in the movement of electrons when a positive rod is brought near a neutral sphere. Grounding the sphere will allow for electrons to flow from the ground back to the sphere, equalizing the charge.

Grounding is used for dircharging..
In case of charging by conduction,let a sphere having excess negative charge is brought in contact with a neutral sphere..Half of the negative charge goes into neutral sphere..But when the former sphere having excess negative charge is grounded,why it becomes neutral? Why does it lose all the charge ?

The transported charge depends on the size of the sphere. The Earth is pretty large.

Yes..It is but why it neutralizes the sphere? Why its different from case when 2 identical spheres ,one negatively charged nd one neutral share charge by conduction?

I think he's saying it shares yes, but depending on size, so if one is twice as big as the other it would get 2/3 the charge and the other would get 1/3, so if one is 100x as large it would get 99.01% of the charge... and so on..

Another way to think of it is in terms of capacitance: Q = CV -> dV/dQ = 1/C. If you discharge to something with low capacitance (your sphere) then it's voltage will change fairly quickly, perhaps not allowing you to totally discharge. If the capacitance is huge (earth), then voltage will remain constant allowing full discharge.

Oh..I understand now.. Thank u all

In case of charging with induction,when a positive rod is brought near the left side of neutral sphere,electron start moving to left and right side becomes postive due to lack of electrons.Now if we ground that sphere from right side and don't move the rod?Will electrons flow from ground to the sphere ?

What is grounding used for in the case of charging?

Grounding is used to safely discharge any excess electrical charge that may have accumulated during the charging process. It helps prevent potential electrical hazards and protects both the charging equipment and the individual using it.

Why is grounding important during charging?

Grounding is important during charging because it ensures that any excess electrical charge is safely directed to the ground, rather than potentially causing damage or harm. It also helps to maintain a stable and consistent flow of electricity during the charging process.

What happens if charging is not properly grounded?

If charging is not properly grounded, there is a risk of electrical shock or damage to the charging equipment. Without a proper ground, any excess electrical charge may build up and cause a surge, leading to potential hazards.

How is grounding achieved during charging?

Grounding is achieved by connecting the charging equipment to a grounding wire or rod that is securely and directly connected to the ground. This allows any excess electrical charge to flow safely away from the charging equipment and into the ground.

Can grounding be used for any type of charging?

Yes, grounding can be used for any type of charging, whether it be for electronic devices, vehicles, or other equipment. It is a standard safety practice that should be followed during all charging processes to prevent potential hazards.
