如果你有一片水果,几个钉子和一些电线,那么你就可以产生足够的电来打开一个灯泡。制作水果电池既有趣、安全又简单。
要制作电池,您需要:
以下是如何制作电池:
以下是关于柠檬电池的科学和化学反应(你可以尝试用其他水果和蔬菜制作电池):
以下是额外的研究机会:
...寿命? 答案 超级用户贡献者Ravexina为我们提供了答案: Batteries have a finite life and there are many different aspects involved, however, the one we are concerned about here is cycle life. The cycle life is the number of complete charge/discharge cycles that a battery is able t...
...drop by a designated e-waste center that specifically accepted lithium-ion batteries. This is important! Throwing potentially inflammable materials in with regular trash is bad (only you can stop fires)! There is likely no need to panic if it is just a week or two until you can properly dispose of i...
...a decent solution, although most of our newer electronics have pretty good batteries, historically we’ve gone the upgrade route. It doesn’t make sense to use a 1200 mAh battery in your cellphone if you can get a cheap 2000mAh battery that fits in the same space. Xaviant比简单切换更进一...
...he battery “rotating” idea does not make sense electrically unless the batteries are in parallel (rarely used that way). Nearly all battery circuits are in series (which you can tell if their polarity is reversed one from another within the battery compartment). The resistance of a weak battery ...
...池的寿命: I have two tricks I use for getting more juice out of my batteries before throwing them away. The first is “the swap” and the second is “the conveyor”. I’m not sure why this works (maybe the individual terminals in electronic devices don’t have equal pull from the batteri...
用干冰冷冻水果。水果里会充满二氧化碳气泡,就像苏打水一样。这种起泡的水果很适合单独食用,也可以在食谱中使用。 起泡水果原料 干冰 果 塑料碗 这个项目只需要两种原料:干冰和水果。确保使用食品级干冰。还...
...正确。确保饮料是凉的,这通常需要在冰上饮用,这是另一个需要记住的重要提示; ...
一个简单的电池可以通过在柠檬中分别插入一段锌和铜来制作。电子通过柠檬汁介质从锌流向铜,产生少量电流。柠檬电池的成功取决于选择最大、最多汁的柠檬,使用尽...
... 在一个典型的水果花束中,水果片被切割并用叉子粘在一起,使它们看起来像花。例如,菠萝环可能被切割成花的形状,每个“花”的中心有瓜球或草莓欧芹等装饰物可以用...
...东,尤其是土耳其、阿富汗和伊拉克的肉菜肴。烤肉串是一个土耳其语单词,意思是“烧焦的”或“烧焦的”,用来形容任何以这种方式烹制的肉。肉通常在串肉机上烹制,然后在明火上烘烤。如果肉也放在烤肉串上,它就被称...
