Answer #1

If we want to calcuate the Gibbs free energy of the system, then system neither energy nor mass can exchange with surroundings. This is possible in isolated system only.

In open systen, system can exchange mass and energy with surroundings.

In closed system, system can exchange energy with surroundings but not matter.

In these two systems energy can be exchange with surrounding then the calculated energy change of the system may be different from the original free energy change of the system.

I'm given a circuit and want to determine whether it's a high-pass, low-pass, band-pass or band-reject - all passive filters. I know I have to determine whether there is an open, closed, or short circuit at the inductor or capacitor (or both) but don't know how to determine these....
