    Entropy And Energy Representation

    How do I go from the entropy of a system, S(U,V,N), to its internal energy, U(S,V,N)? For instance, for an ideal classical gas, we have S=(3/2)N*R*ln(U/N) + N*R(V/N) + N*R*c where R is the Boltzmann constant, N is the particle number, V is the volume and "c" is a constant. How can I...

    How can I simplify a network of capacitors using a Y-Δ transformation?

    I can see it here in the topic O.o Try on these links http://img01.imagecanon.com/full_view.php?view=28670_c4.jpg http://img01.imagecanon.com/full_view.php?view=28671_c5.jpg

    How can I simplify a network of capacitors using a Y-Δ transformation?

    I've made some capacitors association exercices and i got stuck on 2 of them. Q1: Q2: How can i get the equivalent capacitance on this 2 capacitors systems? Ty
