一、实验器材:感应圈(或直流高压电源)、锌板、15瓦的白炽灯泡(好的、坏的均可、只要不漏气。在灯泡玻璃层外侧,对着钨丝的那一面,贴一个4—5平方厘米的香烟盒内的圆金属箔片,接出一根引线作为一个电极,灯丝架焊接一引线作为另一电极)各一。箔片验电器一只,丝绸一块,有机玻璃棒一根。低压电源(或蓄电池组)一只。
First, the experimental equipment: induction coil (or DC high-voltage power supply), zinc plate, 15 watt incandescent light bulb (good, bad can be, as long as no leakage. In the outer side of the glass bulb, facing the side of the tungsten wire, A round metal foil in a 4-5 square centimeter cigarette box is attached, one lead wire is connected as one electrode, and the filament holder is welded with one wire as another electrode). A foil electroscope, a piece of silk, a plexiglass rod. Low voltage power supply (or battery pack) one.
