(b) Consider the diagram of a conducting wire of Figure Q1(b)6). i. Determine the charge of 7.573 x 1017 electrons. ii. If this number of electrons moves uniformly from the left end of the wire to the right end in 1 ms (millisecond), what is the current flows through the wire? iii. How many electrons must pass a given point in 1 minute to produce a current of 10 A? iv. If the charge profile across the cross section of the conductor from left to right is given by g(t) = t + 0.2est C for t2 0 and zero for t < 0, plot the profile of the current that flows across the boundary. In what direction would the current flow? v. Repeat part (iv) for the charge profile (in Coulomb) sketched in Figure Q1(b)(ii).
