If a light bulb is burned out and the switch is on are you still using electricity?
A standard filament bulb works on the principle that it gets hot and glows when a current is passed through it. If the filament has burned out (blown) it is open circuit and no current can flow. Therefore you are not using any electricity even if the switch is still on It may still use power if it is a lighted switch. Find a licensed electrician at www.contraxtor.com
