Very unexpected and unpleasant situation arises when you touch machine door, iron cat or wash hands with water from the crane, and feel at the same time electric discharge. The reasons that objects beat with current can be various, and, having precisely found out all circumstances, it is quite possible to avoid repeated cases.
The most frequent reason of electrization of objects is static electricity. Because of it beats you with current when you take off mittens and you touch the door handle when you iron cat, you comb hair, you open machine door. Especially often these phenomena and meet in the winter in the fall when the summer natural clothes are replaced by woolen jackets, fur coats, kapron tights and also things from synthetic polyester and acetate. The physical nature of this phenomenon is that at contact of two diverse substances, for example, of mitten and hands, there is redistribution of electrons. As a result of friction, or just contacts, on surface the excess electric charge as one substance "tears off" from another electrons is formed. Then you touch with the charged hand the door handle, and at the time of discharging and hits you with current. To reduce the probability of emergence of static electricity, you do not wear clothes from lavsan, acetate, Nitron in combination with silk, wool and nylon. Houses statics can accumulate carpets and plaids from natural wool. From time to time use the spraying antistatic or add when washing conditioners and conditioners with mark "antistatic". That electric discharges are mutually neutralized in humid air (at humidity more than 85% static electricity practically does not arise), you will be able to be helped by humidifier. The same effect will be also from numerous pots with flowers. Other possible reason that objects beat with current, this low-quality grounding of electric devices. In that case you feel discharge, touching the electric device which is switched on in network, for example, to the washing machine or the computer. Perhaps, because of humid air the contact in wires or schemes is broken. You need to repair the equipment. If beats you with current at touch to the battery or when washing hands from the crane, means some irresponsible citizens in your stairwell use pipes as grounding or have just incorrectly connected the washing machine. In that case address to ZhEK, call the electrician and the plumber, they will quickly find such "master".
