The equation in Excel should be of the form: , where A and b are constants. In this case, x is the independent variable representing time, and y is your current measurements. A represents the initial value of the current from , and b represents the reciprocal of the time constant, RC. This means that b = 1/RC. Since RC = (100,000 Ω)(100x10-6 F) = 10 s, therefore the reciprocal should be: b = 0.1. It is this value that want to use to verify the theoretical equation in the Background.
