Explanation:
Suppose the current in a conductor decreases exponentially with time according to the equation I(t)=I
0
e
−t/τ
, where I
0
is the initial current (at t=0) and τ is a constant having dimensions of time. Consider a fixed observation point within the conductor. (a) How much charge passes this point between t=0 and t=τ?(b) How much charge passes this point between t=0 and t=10τ? (c) What If? How much charge passes this point between t=0 and t=∞?
