论文部分内容阅读
在人教版教材中,电磁振荡这部分教学内容,是通过一个演示实验进行引入和分析的。演示实验的电路图如图1所示。先把开关置于电源一边,为电容器充电;再把开关置于线圈一边,使电容器通过线圈放电。观察电流表指针的变化。这个演示实验在本节的
In the PEP textbooks, this part of the electromagnetic oscillation is introduced and analyzed through a demonstration experiment. Demonstration experiment circuit shown in Figure 1. Place the switch on the power supply side first to charge the capacitor; then place the switch on the coil side to discharge the capacitor through the coil. Observe the change of ammeter pointer. This demo experiment is in this section
