We introduce a quantization method of the mesoscopic RLC circuit, basing on the model with coupling of bath and LC system. Quantum fluctuations of the charge and current in the mesoscopic RLC circuit in different states were given. The average of charge and current relates to the eigenvalue of coherent states. Quantum fluctuations of charge and current is independent of the eigenvalue of coherent states.
