What happens when two conducting spheres are connected by a wire?
1: Two conducting spheres are connected by a conducting wire. The charge Q that was originally on the larger sphere distributes itself onto the two spheres. and we find that the charge density is higher on the smaller sphere. Thus, there are more charges per unit area on the smaller sphere than the bigger sphere.
What happens when two conducting spheres touch?
When the two conducting spheres are brought together to touch, it is as though they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres. When the spheres are moved apart again, each one is left with half of the total original charge.
What is the main difference between electric field and electric potential for a solid charged conducting sphere?
electric field: A region of space around a charged particle, or between two voltages; it exerts a force on charged objects in its vicinity. electric potential: The potential energy per unit charge at a point in a static electric field; voltage.
When two conducting spheres are having different charges are joined together by a conducting wire both will have?
the total charge and energy will be conserved.
What happens to charge when two conductors touch?
When two conductors are made to touch, the total charge on them is shared between the two. If the two conductors are identical, then each conductor will be left with half of the total charge. The electrostatic force determines the arrangement of charge on the surface of conductors.
Why is the Electric potential at any point inside and outside a conducting sphere at equal potential?
When a conductor is at equilibrium, the electric field inside it is constrained to be zero. Since the electric field is equal to the rate of change of potential, this implies that the voltage inside a conductor at equilibrium is constrained to be constant at the value it reaches at the surface of the conductor.
How are Electric potential and electric field similar How are they different?
1. Electric field is described as the amount of force per charge while the Electric potential is described as the amount of energy or work per charge. 3. Electric field is a vector quantity while Electric potential is a scalar quantity.
When two charged spheres are connected with the wire the electric charge on them is shared?
If we electrically connect two balls, the charge on the balls would redistribute, so the potential on the both balls is the same. The potential on the ball is the same as the point charge potential. It is directly proportional to the charge and inversely proportional to the ball radius.
Can charge be conserved?
Conservation of Charge is the principle that the total electric charge in an isolated system never changes. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved.
Can two conductors charge each other?
What is the ratio of electric fields between two conductive spheres?
Two conducting spheres of radii r1 and r2 are charged to the same surface charge density. What is the ratio of electric fields near their surface? As the surface charge densities are the same, the total charge on each is proportional to their surface area, kr^2 for some constant k. So the total charges are k (r_1)^2 and k (r_2)^2.
What is the R1 and R2 of a conducting sphere?
In the figure, r1 = 5 and r2 = 7 cm. Before the conducting spheres are connected by the wire a charge of 5×10-7 C is placed on the smaller sphere while the larger sphere is uncharged. Calculate the charge on the smaller sphere after the wire is connected.
What is the potential on the surface of a conducting sphere?
The potential on the surface of a conducting sphere having charge q and radius R is, V = q 4 π ϵ 0 R. Let the charges on the spheres of radii R 1 and R 2 be q 1 and q 2.
How does charge flow from a smaller sphere to a larger sphere?
V = kQ/r so the smaller sphere is at the lower potential (more negative = lower) Negative charge flows from low to high potential so the charge will flow from the smaller sphere to the larger. The flow of charge ceases when there is no difference in potential. Please log in or register to add a comment.
