40 watt light bulb. This is obvious. Go do an experiment. -_-
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.
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.
Input to light bulb is Electricity and output is light.
Thomas Jefferson did not invent the light bulb. The light bulb was invented by Thomas Edison in 1879 in New Jersey.

40 watts. I did an experiment on this. Go do one and see for yourself. Sheesh. -_-
If the current is stronger then the bulb will be brighter.
Yes, they can be used for reading.
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.
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.
A light bulb...LOL jk you cant afford a light bulb so nothing shines in your lamp.
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.
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 ever is reading this you are an idiot
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.
Yes , it is safe to leave a night light on all night , however it depends on the size and 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.
