The current in a wire varies with time according to the relation

i=(3.0\text{ A})+(2.0\text{ A s}^{-1})t

. (a) How many coulombs of charge pass a cross-section of the wire in the time interval from

t=0

t=4.0\text{ s}

? (b) What constant current would transport the same charge in the same time interval?
