Two Way Switch-Switches which can be used in pairs so that either can switch a light on or off. Each switch has terminals allowing them to be linked using Three Core and Earth cable. Voltage (V) - The numerical value of the electrical potential between two points in a circuit.Volts = Wattage/Amperes.lectrical Second Fix-Generally used to refer to that part of an electrical installation that is visible on completion-i.e. the light fitting, wall switches etc. Frequency-In alternating current, the rate at which the current changes direction-in the UK typically 50 Hertz.
To make bleach, a direct electrical current is sent through a sodium chloride solution (table salt and water). This basically splits the atoms leaving chlorine and the caustic soda. Both chlorine and caustic soda (lye) are extremely dangerous. These two chemicals are reacted together to create what we know as bleach.
However, most people when they refer to cleaning with bleach are thinking of household-strength chlorine bleach, a solution of sodium hypochlorite manufactured from chlorine. Non-chlorine bleach is a much milder whitener that can be safely used on colored fabrics to remove stains.It is frequently made with hydrogen peroxide. Oxygen bleach typically refers to a powdered product made with sodium percarbonate, another whitener that can be used on colored fabrics.on-chlorine bleach is a much milder whitener that can be safely used on colored fabrics to remove stains.
