A small insect crawls in the direction of electron drift along bare copper wire that carries a current of 2.56A. It travels with the drift speed of the electron in the wire of uniform cross-section area 1mm^2Number of free electrons for copper =8 times 10^22// ccand resistivity of copper =1.6 times 10^-8 Omega m If the insect starts from the point of zero potential atit reaches a point of ……potential after 10 sec |
