The reading "100W-220V" on an electric bulb indicates that it is a 100-watt bulb designed to be used with a voltage of 220 volts. This information helps ensure that the bulb is used with the correct power supply to operate efficiently and safely.
Yes, they can be used for reading.
A bulb in a lamp converts electric energy into light and heat energy.
Bulbs are typically measured in watts to indicate power consumption, and in lumens to indicate brightness. Wattage is a measure of the amount of power a bulb uses, while lumens measure the amount of visible light the bulb emits. It is important to consider both measurements when choosing a bulb to ensure it meets your lighting needs.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Heat and light.
a bulb is light bulb
It is possible to read by electric light, candle light, or sunlight. Reading was around for a long time before electric lighting was invented. In quantity, between 11 and 60 watts, depending on the type of bulb and type of lightshade.
If the current is stronger then the bulb will be brighter.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Three parts of an electric bulb might include the filament, the actual bulb, and the base.
The electric light bulb came first but was patented later that the telephone was.
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
An led desk lamp is good for reading. It is easier on the eyes than a regular "yellow" bulb. It is also more energy efficient so you will save on your electric bill.

Why is the wet-bulb reading necessary when checking the charge
It depends on the type of bulb.
The electric light bulb was invented in 1879.
