لسعات الكهرباء الساكنة .ما الحل؟

Quote: If a material in the series (e.g. wool) is rubbed against a material lower in the series (e.g.rubber) the higher material (wool) normally charges positive wheras the lower material (rubber) charges negative. The further the materials are apart in the table, the stronger the charging action is expected to be. So polyurethane soled shoes (quite common!) walking on a glass floor (not unknown!) is a recipie for static problems! Unfortunately a shoe sole (e.g. PU walking on PP) which gives low generation on one floor material may give high generation with another (e.g PU walking on glass or nylon)
