摘要
根据灵敏电流计动框的运动理论给出一种确定灵敏电流计外临界电阻值的方法,通过测定灵敏电流计的自由振荡周期和欠阻尼状态下的衰减振荡周期,可以计算出灵敏电流计的外临界电阻值。
Aceording to the motion theory of moving coil of sensitive galvanometer, we can get a method to determine the extermal critical resistance value. By measuring the free-oscillating period of sensitive galvanometer and the damped oscillation period of short damp-ing state,we may work out the extenal critical resistance value of sensitive galvanometer.
