If you take tap water and pass electricity then tap water will conduct electricity but why we were all told not to turn on/off the switches with wet hands.
Statement 1: Tap water contains ions and is good conductor of electricity.
Statement 2: Distilled water and urea does not contain ions.
Water alone does not conduct electricity. If you washed your hands in deionised water (water that has been essentially purified, Distilled water) and then touched a switch, then you would get shock. The reason is that when salts dissolve in water, their ions dissociate, meaning you have positive and negative molecules ready to conduct charge.
