Detailed explanation-1: -Since practically 70% of the body is made up of water, it is considered to be a good conductor of electricity on average. This is due to the ions (i.e. Na+, K+, Cl−) that are contained within the water.
Detailed explanation-2: -As our body cells contain various ions like sodium ion, potassium ion, chloride ion etc which have the tendency to conduct electricity and this makes our body good conductor of electricity.
Detailed explanation-3: -Why does the human body conduct electricity? Our body is composed mostly of water, above and beyond everything else, and while pure water is a very poor conductor, water with any SALTS or ionic chemicals dissolved in it is an EXCELLENT conductor.
Detailed explanation-4: -Electrical conductors, in the most basic sense, are materials that permit electricity to flow freely throughout them. We know that salt water is a good conductor of electricity. Tap water includes impurities, such as dissolved sodium, calcium, and magnesium salts, thus it is an excellent conductor of electricity.
