Electrical Circuit. An electric circuit is a closed system where it contains at least one power source (voltage) and a load (resistance), the load should consume all the energy and transform this energy into another type of energy (Law of Conservation of energy).
An incandescent lamp or incandescent lamp 1 is a device that produces light by Joule heating of a metallic filament, particularly of tungsten, to put at white, by passing electric current. With existing technology, now considered inefficient since 85% of the electricity it consumes into heat and only the remaining 15% into light.
Drivers: all those materials or elements that allow cross the stream flow or moving electric charges. Insulation: not conduct electricity, atoms or stretch or capture electrons. These materials are plastic, mica, glass, rubber, ceramics, etc. All these and other similar materials with similar properties, total resistance opposing the passage of electric current.
