Alternating CurrentHard
Question
A broad metal plate is connected to earth through a conducting wire as shown. An electron flies with constant velocity along a straight line above the plate at a distance much less than the linear dimensions of the plate. If the current I flowing from the earth to the plate is considered to be positive, then which of the following graph correctly depicts the variation of current I with time?
