Though the above nodes capture the essence of the bug zapper, I was surprised to notice that neither give technical details on the workings of those technological marvels (or, as we could learn, nugatory and even detrimental items of expertise). Bug zappers had been created in 1934 by William F. Folmer and Harrison L. Chapin. Since then, little has modified in the elemental design of the zapper. The bug zapper is normally formed like a lantern, with an electrically grounded housing and, as speedo notes, is surrounded by a wire mesh that prevents kids or squirrels from being subjected to electrocution. A fluorescent gentle, usually of the blue ultraviolet selection, attracts insects. Surrounding the light are two layers of wire mesh, separated by a hole the width of your common insect. These wire meshes are electrified by a transformer that ups the 120-volt current that powers the zapper to 2000 volts or more.
