    Find io from the graph. Find the time constant RC = io/e where e = 2.71828.
    From RC you can find R.

    We know from the theory that the current vs time function is:

    [tex]I(t)=I_0e^{\frac{t}{RC}}[/tex]

    Now you can see that when the current is the e-th part of I_0 i.e. I=I_0/e then the time is [tex]t=RC[/tex]

    Now try to calculate R.
