Homework Statement
Assume that the switch in the figure has been closed for a long time and opens after in t=0.
Find Ix in a) 0- b)0+ c) 40ms
The Attempt at a Solution
Switch is opened in t=0, current flows only in the 10Ω resistor, Ix=3v/10Ω= 0.3A-> 0-
0+ --> 3v/10=0.3A
Not sure if both currents are the same, and for the 40ms, when solving the equation (τ=L/R) τ (tau) results in a small number.
