特点:用铝箔作导线质轻且制作方便,演示效果明显。制作方法:结构如图。 1.直导线:拆取大容量电解电容器内铝箔,抹平后截取20×5厘米~2两条铝箔带,用直径约1.5匣米的圆捧(可用静电实验中的起电棒)作骨架,把铝箔卷成圆筒,在其接缝处用胶水纸粘牢,作直导线之用(同法做两根,即图中“A”、“B”)。再截四条25×1.5厘米~2的
Features: The use of aluminum foil for the light weight and easy production, the demonstration effect is obvious. Production method: structure as shown. 1. Straight wire: Take away the aluminum foil from the large-capacity electrolytic capacitor. After smoothing, cut two aluminum foil strips of 20×5 cm to 2 mm. Use a circle with a diameter of about 1.5 μm (a static electricity rod in an electrostatic experiment) as the skeleton. The aluminum foil is rolled into a cylinder, glued with glue paper at its seams and used as a straight wire (doing two with the same method, ie “A”, “B”). Then cut four 25×1.5 cm~2
