Hydrocarbons have no free electrons, thus they cannot conduct electricity. Petrol, Diesel and Kerosene are bad conductor of electricity.

In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

Molten sodium chloride conducts electricity because of the movement of the ions in the melt, and the discharge of the ions at the electrodes. Both of these have to happen if you are to get electrons flowing in the external circuit.

So, sodium chloride does not conduct electricity in a solid-state. In a molten state, sodium chloride dissociates into a sodium ion and chloride ion and these ions conduct electricity.

Petrol and kerosene oil have very low electrical conductivity and hence they are poor electrical conductors (i.e. insulators).

Milk is a good conductor of electricity because it contains water and acid. And water becomes a good conductor of electricity in presence of acid. So due to presence of water and lactic acid in milk, it is good conductor of electricity. honey is bad conductor and milk is good conductorof electricity.

Tap water is a good conductor of electricity as small amounts of mineral salts are naturally present in it.

That means Pure water is a bad conductor of electricity. water is good conductor of electicity because in it there are many electrolysis and pure water is bad conductor of electricity so in pure water we add a few drops of sulphuric acid to make it good conductor of electicity.

Molecular liquids do not conduct electricity. Many organic liquids are molecular. Examples include benzene, acetone, methanol, ethanol, glucose, all the alkanes, and all the alkenes. Mineral oil is non-conductive.

The answer is in our sweat. Unlike the epidermis and dermis layers of our skin — which are poor conductors of electricity — our sweat is rich with electrolytes such as sodium and chloride, which makes our sweat a surprisingly decent conductor of electricity (though not quite as good as metal).

Skin is actually a very good insulator as well so, relative to metal, humans aren’t very good conductors. However, it is things such as the ionized water and whatnot that make up our body that do cause us to conduct.

When a wire is connected to a working electric circuit, the copper atoms’ footloose electrons begin to drift in a particular direction. Like copper and other metals, the human body is also a good conductor.

Skin does conduct electricity but has fairy high resistance, about 100000 ohms, which varies depending on how damp the skin is.

Electric current in the human body is dangerous for two primary reasons. First, it disrupts the normal operation of your nervous and muscular systems, causing severe muscle contractions. Second, just like in the light bulb, when current passes through your body, it’s transformed into thermal energy.

Corona appears in the transmission line when the surface voltage gradient at the line conductor reaches the breakdown stress. Due to corona, heat and bluish light produce. There is a loss of power and energy dissipation. This loss is known as the corona loss.

Skin effect is the tendency for high-frequency currents to flow on the surface of a conductor. Proximity effect is the tendency for current to flow in other undesirable patterns—loops or concentrated distributions—due to the presence of magnetic fields generated by nearby conductors.

2. SKIN EFFECT • The non-uniform distribution of electric current over the surface or skin of the conductor carrying a.c. is called the skin effect. The concentration of charge is more near the surface as compared to the core of the conductor.
