An isolated conducting sphere has a 8.2 cm radius. one wire carries a current of 1.32 a into it while another wire carries a current of 1. a out of it. how long in seconds would it take for the sphere to increase in potential by 1500 v? number enter your answer in accordance to the question statement units choose the answer from the menu in accordance to the question statement

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
