取材与制作:1．铜(薄)片3×4cm~2,锌(薄)片或选用干电池上的锌皮3×4cm~2也可,要求锌的纯度较高．2．两根长4~5cm,∮8~10铜芯皮线。用电烙铁将两根铜芯线一头分别与铜、锌片3cm边中间处焊接上,焊接处用稀盐酸洗擦。3．木条8×3×1cm~3,距两端3cm处打两个小孔,将铜芯皮线穿入,作铜、锌片支架。4．40cm长导线两根,将一头,与铜锌片支架上方的铜芯线焊接上。5．250ml烧杯一只。
Materials and production: 1. Copper (thin) film 3 × 4cm ~ 2, zinc (thin) film or use of zinc battery on the dry cell 3 × 4cm ~ 2 can also require higher purity of zinc. 2. Two long 4~5cm, 8~10 copper cores. Use a soldering iron to solder the two copper wires to the middle of the 3cm side of the copper and zinc sheets respectively. The joint is washed with dilute hydrochloric acid. 3. The wooden strips are 8×3×1cm~3, and two small holes are drilled at 3cm from both ends, and the copper core thread is penetrated into the copper and zinc sheet brackets. Two 4.40cm long wires, one end, and the copper wire on the top of the copper zinc sheet bracket welded. 5.250ml beaker one.
