The light bulb. The light bulb. The light bulb.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.

If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
He was a light bulb inventor.
who invented the light bulb and why did they do it Thomas Edison. Because he was an inventor.
Lewis howard latimer
Thomas Edison who invented the light bulb
The light bulb had already been invented, Cruto was an Italian inventor who improved on Thomas Edisons incandescent light bulb Alessandro Cruto in 1881
Albert Einstein did not invent the light bulb. The light bulb was actually invented by Thomas Edison in 1879. Einstein's contributions were in the field of theoretical physics, particularly with his theory of relativity and the famous equation E=mc^2.
thomas Edison invented the light ballWRONG Tomas Edison invented the light BULB!!!! NOT LIGHT BALL
No, Britain did not invent the light bulb. The light bulb was invented by Thomas Edison in the United States in 1879. However, Joseph Swan, a British inventor, also independently developed a working light bulb around the same time.
Edison didn't work in physics. He was an inventor and had an inventor's workshop and invented the light bulb.
Thomas Edsion invented the phonograph and the light bulb.
Theodore Edison
No, the light bulb is not named after James Watt. The light bulb was actually invented by Thomas Edison. James Watt was an engineer and inventor known for his work on improving the steam engine.
