Over time (0s ≤ t < ∞), charge enters an element according to q(t) = 7.5C · (1 − e^{(+t/τ)}).

1. What is the current into the element as a function of time? (Find a symbolic answer!)

2. What is the unit of τ?

3. Prove that the unit of the result indeed is A.

3. The attempt at a solution

Do I need to take the integral of this to get current as a function of time? I don't suppose I cane just separate the coulomb int A*s and get the A by itself or is that not right?

And I dont know where else to go on this problem...
