A charged belt, 35 cm wide, travels at 35 m/s between a source of charge and a sphere. The belt carries charge into the sphere at a rate corresponding to 100 a. Compute the surface charge density on the belt. A fuse in an electric circuit is a wire that is designed to melt, and thereby open the circuit, if the current exceeds a predetermined value. Suppose that the material to be used in a fuse melts when the current density rises to 490 a/cm2. What diameter of cylindrical wire should be used to limit the current to 0. 65 a? m: /1 pointshrw9 26. p. 022. The legend that benjamin franklin flew a kite as a storm approached is only a legend - he was neither stupid nor suicidal.
