Connecting a light bulb's electrical contacts to the positive and negative terminals of a battery causes it to turn on and to draw power from the battery. The key to successful connection and operation is matching the bulb's operational range with the battery's voltage.Know More
Contacts differ from bulb to bulb. Some are prongs extending from the bulb's base below the threading while others include a threaded contact and another, smaller one without threads extending from the base. Spring contacts, found in most flashlights, are a good connector.
Good combinations of bulbs and batteries according to capacity include:
Batteries improperly matched to light bulbs will not light the bulbs effectively. If their voltage is too low, the bulb will produce no light. If it is too high, the bulb's filament could be vaporized and the bulb will be rendered useless. A close match might work, but it is unlikely to be as effective as a perfect match between voltage and capacity. Bulbs function inside a target temperature range rather than on a spectrum of effective light production.Learn more about Physics
Thomas Edison is typically credited with inventing the light bulb in 1879. However, he was not the only person in history to have contributed to the development of the modern incandescent light bulb.Full Answer >
A light bulb diagram is a drawing showing the construction of a light bulb. A light bulb is a source of electric light that works through incandescence, which is the production of light as a result of heating the filament.Full Answer >
A mogul base light bulb is a light bulb that has a larger screw base than a standard screw base bulb. The screw base of a mogul bulb is 39 millimeters across, while the base for a standard bulb is 26 millimeters across.Full Answer >
A potato helps power a light bulb by acting as both a bridge and a separator for two electrodes made of different metals. The two metals most frequently used are zinc and copper because of their ubiquity and difference in electron affinity. The acid in the potato starts the reaction, and the electrolytes in the potato allow a flow of electrons, an electric current, to flow between the electrodes.Full Answer >
