Question

Electrostatic charge do not work during humind days? why.

Answer 1

When it is humid, atmospheric water molecules will adhere to dielectric materials creating a microscopic layer of water and other contaminants, e.g., salts, hydrocarbons, and miscellaneous polar molecules. This layer will reduce the surface resistivity of the dielectric reducing the amount of force, and thus, the amount of time required for a negative charge to travel across the surface and recombine with a positive charge. Thus, humidity reduces the total amount of charges that can be isolated on a dielectric surface, as well as the amount of time the charges will remain separated.
May be right.
