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 in Physics
Thomas Edison is credited with inventing the light bulb. He and his team worked on and tested over 3,000 bulbs, and in 1879, Edison was granted a patent for the first commercially successful light bulb.Full Answer >
According to the California Science Center, a light bulb can work with a lemon by utilizing electrolytes within the lemon as a source of electricity. This is only enough electricity to power a small light, such as a 5 VDC 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 >
