嘗試重現觸電筆的觸電感覺(20點)

2009-10-11 2:29 am
相信不少人知道市面上有整人的觸電筆。我想用兩顆乾電和銅線重現小型觸電的感覺,但只能令銅線和電池變得很熱卻不能得出觸電的感覺。請問實質上的方法和結構是如何呢?

✔ 最佳答案
Your battery just heats up the wire, as this is almost a short-circuit. That's why you only feel hot when touching the wire.
Generally, dry cells only provide low dc voltage. Such low voltage will not casue any feeling of elctric shock. You need to raise the voltage of the dry cell, either by electronic means or by an induction coil, to hundred or thousand volts in order to get the shock feeling.

You Can Let A Electrical Appliance Be Leakage,But The Current Of Leakage Must Not Exceed 30mA,Than The Leakage Current Will Flow Though Out Body Bt Using AC220V Current.
Or You Can Stick Your Finger Into AC220V Socket(Hot Wire),You May Get Electrocuted.

這是因為電阻的問題,首先我們要知道若有2條物體,當

電流在分叉路時,電流會流去電阻較低的一方。

就像你做的實驗一樣,人手指的電阻比銅線大,所以電流不會

流向你手指,所以你感受不到電力。
