An LR circuit is constructed using a (10.0 +/- 0.1) ohm resistor and a (330 +/- 3) mH inductor. This circuit is charged and the values returned from the exponential fit (y=Ae^(-Cx)+B) are : A=1.88(10)^-3 ,B=2.6(10)^-4, and C=1898.4
A) Calculate the time constant (and uncertaintity) from the values of R and L
B) Determine the value of the time constant from the exponential fit.
C) Determine if the constants from Part A and Part B agree.
