Suppose the current in a conductor decreases exponentially with time according to the equation I(t) = I0e-t/?, where I0 is the initial current (at t = 0), and ? is a constant having dimensions of time. Consider a fixed observation point within the conductor. (Use the following as necessary: I0 and ?)

(a) How much charge passes this point between t = 0 and t = ?? (If applicable, round any coefficients to 3 decimal places.)
Q(?) =.............

(b) How much charge passes this point between t = 0 and t = 10?? (If applicable, round any coefficients to 5 decimal places.)
Q(10?) =...........

(c) How much charge passes this point between t = 0 and t = ? (If applicable, round any coefficients to 3 decimal places.)
Q() =............
