Eye floaters and flashes are both caused by the natural shrinking of the gel-like fluid in your eye (vitreous) that happens as you age. Floaters appear in your field of vision as small shapes, while flashes can look like lightning or camera flashes. Floaters are very common and typically don’t require treatment.
An arc flash is the light and heat produced from an electric arc supplied with sufficient electrical energy to cause substantial damage, harm, fire, or injury. Electrical arcs experience negative incremental resistance, which causes the electrical resistance to decrease as the arc temperature … Visa mer An arc flash is the light and heat produced as part of an arc fault, a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system.
