The quantity of charge Q in coulombs (C) that has passed through a point in a wire up to time t (measured in seconds) is given by Q(t) = t3βˆ’ 4t2 + 6t + 2. [See this example. The unit of current is an ampere 1 A = 1 C/s.](a) Find the current when t- 0.6 s. (b) Find the current when t1 s X A At what time is the current the lowest?
