Electrical Current I (t) in some discharging circuit is expected to decay linearly with time, according to the formula: I (t) = I0 at, where I0 = I (t = 0) and a is a constant. Graph below shows two measured data points. (a) Find I and 15 values corresponding to these two measurements and their uncertainties (you can neglect taxis uncertainty for the rst data point). (2 points) (b) Find the best estimate of constant a and its uncertainty, Ad. (8 points) 12 10K I [A] 0.00 0.05 0.10 0.15 0.20 t [sec]
