25.7 • CALC The current in a wire varies with time according to the relationship 1 = 55 A - (0.65 A/s2)12. (a) How many coulombs of charge pass a cross section of the wire in the time interval between t = 0 and t = 8.0 s? (b) What constant current would transport the same charge in the same time interval?
