when i connect a sinusoidal voltage source to resistors all voltages and currents become zeros. another problem is how to plot the voltages and currents for any component. if anybody has a book or link it would help please reply. thank you check the attached picture

Homework Statement So I got this homework to do, and I've pretty much figured it all out using a bus diagram, except for one part. I don't know how to approach Resistors 7 through 9 and 10 through 12. The only idea that I have is that they equalize between 7 and 8, and 10 and 11. This...

Given the following circuit: (see attached file) find the Network Function between I_L, flowing as drawn in picture, AND I_g. I guess all the calculation should lead up to an expression like this one: I_L(s)=F(s) I_g(s), where F(s) is a function in "s" which corresponds to the NETWORK FUNCTION...

This is not homework, but a question I have posed for myself. In a linear, passive, 3-terminal RC network for sinusoidal voltage input how many resistors and capacitors are required to give an open-circuit voltage gain of 2? I've found some very complicated networks, but I'd like to find...

I have a question... If you have a unsecured network, is it possible to track users hooked up to your network? Say neighbours? If so, how do you do it? And, can you prevent them from logging on to your network without using a secured network?
