Please answer #4 only. See attached file for full problem description.
In the following circuit, the voltage source is turned on at t =0.
The current flowing in the inductor is given by
a) find the coefficients A and B.
b) Find L, R< and v0.
Please see the attached file.
(a) when t = 0, the current in the inductor is 0, so
The voltage of the inductor is 0 when t = 0 as well. So
Substitute B to (1)
Output of the circuit is found. The solution is detailed and was rated '5/5' by the student who posted the question originally.
