Hi
I have the following task, I've managed to do the first part but was needing some help for the second.
The circuit can be seen below (please note a switch exists between the supply and L1):
Via the use of Mesh analysis, determinents and patial fractions I have found the currents in each branch and therefore the total current as well, my workings can be seen in the attached PDF.
The question I'd like some help with is:
The second part asks for the voltage to be calculated across the centre branch at the following times (s) after the switch has been closed:
0, 1, 10, 100, and at 't' infinity.
Now I understand that in a DC circuit the inductor will offer no impedance after a certain length of time, and in an AC circuit the impedance of an inductor is 2*pi*f*l but how is it dealt with in the example above?
