Passive RL Circuit Natural Response

Purpose:

Prelab: 

The requirement of this lab is almost similar to the previous lab which is RC Circuit Natural Response.
We calculate V(t) of Inductor at t>0 and then calculate the value of Tau theoretically and experimentally.

The i_L(t) = 0.05e^(-t/Tau), theoretical Tau = L/R2 = 2.128 x 10^(-5) s.
Then value of V_L(t) can be calculated by Ldi/dt. V_L(t)= (-0.05/(2.128x10^(-5)))e^(-t/Tau)

We use the same method as previous lab which is choosing V1,V2 and delta t to find experimental Tau.
The value of experimental Tau = 2.017 x 10^(-5) s
%Diff= 5.5 %
In this experiment, the time constant Tau is L/R, but R is only R2 since we unplug R1.

Here is the picture of our result by using Digital Analog.
