实验启示我们,传统的自感现象实验对实验器材提出了较高的要求,并不是任何一个线圈和任何一个小灯泡都能产生明显的实验现象.例如,在通电自感实验中,要求自感线圈L和灯泡A组成的RL电路的时间常数τ足够大,这样才能观察到明显的灯泡逐渐变亮的过程.除此,即使可以观察到灯泡亮度 Experiments have shown us that the traditional self-inductance phenomenon experiment put forward higher requirements for experimental equipment, not any one coil and any small bulb can produce obvious experimental phenomena.For example, in the power of self-inductance experiment, self-inductance The time constant τ of the RL circuit composed of the coil L and the bulb A is sufficiently large so that a noticeable bulging of the bulb can be observed. In addition to this, even if the bulb luminance
