Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be...

Hi PeroK, thanks for the reply. "Inside a uniformly charged spherical shell, the electric field is zero." For the case of concentric spherical surfaces, this does make sense for the inner sphere; the electric field within the inner sphere is 0. However, does this argument extend for the outer...

Hi, thanks for the reply. I’m not exactly familiar with the shell theorem for electrostatics, is it that a spherical shell would behave exactly like a point charge with the same charge (outside of the shell)? How would this idea address my question? Thanks.

Hi all. I have a question regarding Gauss law. I have learnt that Gauss law applies irrespective of external charges. However, there is a situation which I can seem to reconcile. Consider the case of a coaxial cable, with two concentric conductors separated by a layer of air. The electric field...
