Number 2 Only. See attached file for full problem description.
In the following circuit, all of the resistors R are identical, i1(t) is the input current and i2(t) is the output current. Calculate the step response of the system. i.e., calculate the output i2(t) when the input is a unit step function.
Please express your answer as a function of time, in terms of the parameters L and R.
The solution explains how to calculate the step response of the system.
