We see in picture that the field is Blank at the high point of the bottom conductor (the earth).target 1 of 2 This is where the air is mostly likely to break down and become conducting and allow the opposite charges to rush toward each other creating Blank.

Storm clouds may build up large negative charges near their bottom edges. The earth is a good conductor, so the charge on the cloud attracts an equal and opposite charge on the earth under the cloud. The electric field strength near the earth depends on the shape of the earth's surface, as we can explain with a simple model. The top metal plate in Figure P20.32 has uniformly distributed negative charge. The bottom metal plate, which has a high point, has an equal and opposite charge that is free to move. a. Sketch the two plates and the region between them, showing the distribution of positive charge on the bottom plate. b. Complete your diagram by sketching electric field lines between the two plates. Be sure to note the direction of the field. Where is the field strongest? c. Explain why it is more dangerous to be on top of a hill or mountain during a lightning storm than on level ground.

(II) Draw a conductor in the oblong shape of a football. This conductor carries a net negative charge, $-Q$. Draw in a dozen or so electric field lines and equipotential lines.
ELECTRIC POTENTIAL
Electric Potential Energy and Potential Difference
In good weather and due to the presence of positive charges in the ionosphere, the surface of the Earth (considered as conducting) becomes negatively charged by influence. Some equipotential contours are shown in Figure 1 below. The tree and the ground are at the reference potential, V = 0V. 1. Draw electric field lines through points M, N, O, P, Q, and R. Draw the field lines, In which regions is the electric field uniform ? Where is it strongest ? Figure 1: Fair weather equipotentials.
