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.
We know how to find the electric field caused by a single point charge. We will find the electric field E1 caused by charge q1, the electric field E2 caused by charge q2, and the electric field E3 caused by charge q3. The net electric field Enet is the _vector_ sum of these three fields,
