| 摘 要： | By virtue of the generalized Hellmann--Feynman theorem forthe ensemble average, we obtain the internal energy and average energyconsumed by the resistance R in a quantizedresistance--inductance--capacitance (RLC) electric circuit.

| Abstract: | By virtue of the generalized Hellmann--Feynman theorem forthe ensemble average, we obtain the internal energy and average energyconsumed by the resistance $R$ in a quantizedresistance--inductance--capacitance (RLC) electric circuit. We alsocalculate the entropy-variation with $R$. The relation between entropyand $R$ is also derived. By the use of figures we indeed see that theentropy increases with the increment of $R$. |
