This article utilized the stochastic theoretical method to reseach the thermal fluctuation of the resistance in RL serial circuit influence on the current transient process and calculated the stationary state probabity density of the current, the average current and the fluctuation of the current. The result showed that the thermal fluctuation intensity of the resistance have a great influence on the current transient process. When the temperature turned highly and variated unstably, the change law of the current appeared obvious randomness.
