Static shocks and how to avoid them q card gas station


Static electricity is generated whenever two materials are in contact with each other. All materials are made of electrical charges in the material atoms. electricity history timeline In the universe there are equal amounts of negative electrical charge (electrons) and positive charge (protons). These generally try to stay in balance of equal amounts at every location.

However, when two materials are in contact, some of the charges redistribute by moving from one material to the other. This leaves an excess of positive charge on one material, and an equal negative charge on the other. When the materials move apart, each takes it’s charge with it. types of electricity tariff One material becomes charged positively, and the other negatively.

If the materials are able to conduct electricity away the charges will dissipate and eventually recombine. In this case, static electricity effects may be too small to be noticed. However, if the charges are separated faster than the material can dissipate them, the amount of electrostatic charge builds up. Eventually a high voltage, and the effects of static electricity, may be noticed.

When you sit in a chair the contact between your clothes and the chair can generate a lot of electrostatic charge on your clothes. While you stay in contact with the chair your body voltage stays low. If you lean forward so you back moves away from the chair back, or if you get up out of the chair, then you take the electrostatic charge with you. Your body voltage can rise very rapidly to a high voltage as the charge is separated from it’s counter charge on the chair.

When dust travels in the air sucked through a vacuum cleaner it impacts on the pipe walls and other internal parts. These impacts generate static charges on the particles and on the pipe walls. k electric bill statement If these parts are made from plastics or other insulating materials they can charge up and give static shocks. Rotating parts such as carpet beaters can also charge up through rubbing action. If the suction pipe has a metal coil and is not earthed, this can charge up and give quite an energetic spark.

If the wall or door is made of wood, concrete or some other material that has low or intermediate conductivity, any static charge on your body escapes slowly and usually does not cause a shock. la gas prices If you touch metal, water, or another person when your body is highly charged, the charge is discharged quickly as the material is highly conductive. In this case you may feel a shock.

Static charge build-up is enhanced when the air is dry. So, static problems and effects are often noticed in dry air conditions. The air outside can be very dry when the weather is cold and dry. Indoors, central heating or air conditioning can give very dry conditions which promote static electricity. Heating warms the air and reduces its humidity.

Unfortunately cure is not always easy. Indoors, you can try raising the air humidity to 40-50% rh with a humidifier. (You can check the humidity with a cheap humidity meter from a gardening shop.) Also, look for shoes with leather soles. In the electronics industry, and in areas where electrostatic sparks could cause a fire hazard, people often wear specially designed static dissipative shoes to reduce electrostatic charge build-up on the body. gasbuddy touch It is less likely that problems will be experienced with non-polymer floors, such as cement or wood (although varnishes can cause problems). However, replacing the floor can be expensive!

Sitting in the car, electrostatic charges are generated on the car seat and the person’s body, due to contact and movement between the clothes and the seat. When the person leaves the seat, They take half of this charge with them. As they get out of the vehicle, their body voltages rises due to this charge – a voltage of 10,000 Volts is not unusual.
