Who invented the electric light bulb what year was it invented and why was it necessary?
The first electric light was made by Humphry Davy in 1800. But it was not practical. A practical light bulb was developed by Thomas Edison in 1879. The light bulb revolutionized the world by making it possible to carry on near normal behavior at night. Prior to the light bulb people had only the dim light of candles and flame lamps.
Was the idea of the light bulb welcomed?
At first people thought it was a sign from the devil, a human being able to see at night. The Roman Catholic Church banned the idea of the light bulb because they thought if God wanted us to see at night then the moon would be brighter.
What is the input or output of the light bulb?
Input to light bulb is Electricity and output is light.
When and where did Thomas Jefferson invent the light-bulb?

What is the minimum watt of a light bulb 30 40 50 60 or 70 watt for night reading?
40 watts. I did an experiment on this. Go do one and see for yourself. Sheesh. -_-
What is the connection between the reading and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.
Can a light bulb be used for reading?
Yes, they can be used for reading.
How do you test a light bulb with a voltmeter?
To test a light bulb with a voltmeter, set the voltmeter to measure AC voltage. Then, place the voltmeter probes on the metal contacts at the base of the light bulb. If the light bulb is working properly, the voltmeter should display a voltage reading. If there is no reading, the light bulb may be defective and needs to be replaced.
How did the light bulb help?
The invention of the light bulb made it possible to work longer hours. It increased safety in the workplace. The light bulb replaced oil lamps in homes. The oil lamps were fire-hazards. People found that they could enjoy leisure activities such as reading at night time.
What shines at night time?
A light bulb...LOL jk you cant afford a light bulb so nothing shines in your lamp.
What is the connection between the reading and brightness of the bulb?
The brightness of a bulb is directly related to the amount of light it emits, which can affect the ease of reading. A brighter bulb typically provides more illumination, making it easier to read in low-light conditions. Conversely, a dimmer bulb may strain the eyes and make reading more difficult.
How long does a night light bulb last when used continously?
A night light bulb typically lasts around 1,000 to 2,000 hours when used continuously. This can vary depending on the type and quality of the bulb.
Who persuaded Edison to invent the light bulb?
who ever is reading this you are an idiot
How can I use a multimeter to test a light bulb?
To test a light bulb using a multimeter, set the multimeter to the resistance or continuity setting. Touch one probe to the base of the bulb and the other probe to the metal threads at the bottom of the bulb. If the multimeter shows a reading, the bulb is functioning. If there is no reading, the bulb may be faulty and needs to be replaced.
Is it safe to leave a night light on all night?
Yes , it is safe to leave a night light on all night , however it depends on the size and the bulb.
What are the minimum requirements in order to light the bulb?
To light a bulb, you typically need a power source (such as a battery or electrical outlet), a conductive material to connect the bulb to the power source (such as wires), and a functioning bulb itself. When these components are properly connected and the power is supplied, the bulb should light up.
