What does a source of electrical energy do in an electrical circuit? Imagine the electrical circuit as water channels, containers and such. In order for the water to flow in those channels, you need to raise to water high enough or provide enou â¦ gh water pressure to go through thick and thin pipes and fill in the containers.
The electric field must be zero inside the solid part of the sphere Outside the solid part of the sphere, you can find the net electric field by adding, as vectors, the electric field from the point charge alone and from the sphere alone We know that the electric field from the point charge is given by kq / r 2.
