Question

You have a summer job with the power company investigating the vulnerability of power lines to natural disasters. Your task is to determine the possible electrical surges on power lines from the high electric fields caused by lightning. You notice that the metal support pylons are not grounded and, therefore, you hypothesize that nearby lighting could uniformly charge the pylons. You realize that you can derive a formula for the electric field along the length of the wires as a function of the height of the pylon and its charge density. To make the calculation simpler, you assume that the pylon consists of a single vertical pole, with the power lines supported at the midway point. How did you derive the formula for the electric field? inon lines from the ng are not grounded and.

    1. Parallel plates. You have two equal but oppositely charged parallel conducting plates, separated by 10 cm. A voltmeter shows that the potential difference between the plates is 500 V. (a) Which is at a higher potential, the positive or negative plate? (b) How big is the electric field between the plates? (c) You let go of an electron next to the negative plate. How much work does the electric field do in moving the electron to the positive plate?...
