Probably the '1' got scrubbed out somehow.
A zero-watt bulb is a lightbulb that uses little power. Contrary to the name, these bulbs are not in fact zero watts. The reason they are colloquially called "zero watt" bulbs is because when they were first made, they only had a power consumption rate of 15W but testing equipment at the time was unable to detect such low wattage causing people to think they didn't use any power. Todays "zero watt" bulbs are as little as 10W. +++ Hardly "zero watt" then. I wonder if the term was originally an advertising slogan as misleading as "zero carbon homes", because I cannot believe it was impossible to measure a power below 15W at the time these lamps were invented, even if indirectly from the Voltage and Current. (W = V x I ).
If you turn a 60 watt light bulb on and off, it will still consume 60 watts when it is turned on. The act of turning it off does not reduce its power consumption when it is on. However, when the light bulb is turned off, it consumes no power.
it will take more than100 watts until the filament reaches operating temperature so perhaps a second to get as low as 100 watts . then 100Watts there after until 300 hours pass then 0 watts if you mean 100Watt hours then the answer is 1 hour and the hour will cost about a penny
Fluorescents are always 3-4 times more efficient than halogens which are a version of incandescent bulb.
That depends on you. If you want, you can say 1 watt should be 0 dB.
A 0 Watt bulb does not consume electric power so the cost is zero.

If you are classing a zero watt bulb as one that glows as does a neon bulb then it is not a zero watt bulb. A neon bulb has no filament between the electrodes When energized it glows because of the inert gas neon within the glass envelope. These type of bulbs do not use a wattage rating when sizing them for an application. These types of bulbs are used mostly in pilot light applications. The lamp takes a starting voltage of 60 -110 volts AC to ionize the gas and start the glow. Once started the lamp can maintain conductivity with a reduced voltage of 20 to 30 volts. Once this conductivity starts the current needs to be limited. The use of an external resistor in series with the lamp is what is used to control the current. However, the neon bulb still pulls current and thus power, so it is not a 0 watt bulb. There is no such thing as a zero watt bulb. With no power, you cannot interact with anything.

Here's how to convert dB units (with usually a 1 Watt or whatever 1 value as reference) to dBm units (with a 1 miliWatt reference value):x= value to be convertedx [dB]= x + 30 [dBm]Proof:P= 1 Watt--> 10*log10(1)= 0 [dB] (this is 1 Watt in dB)--> 10*log10(1/(1*10^(-3)))= 10*log(1*10^3)= 30 dBm (this is 1 Watt to dBm)Now, if you do whatever number of examples you want to do, you'll end up in concluding the conversion dB to dBm is totally linear without of actually having to proof the linear properties. (i'm too lazy to write it here).Hope this helps....Regards,STMI
10-0 is actually 10 :)
In 1974, Eddie Watt played in 42 games, all for the Philadelphia Phillies, and batting in all of them. He had 1 at bat, getting 0 hits, for a .000 batting average, with 0 runs batted in. He was walked 0 times. He struck out 0 times.

In 1967, Eddie Watt played in 49 games, all for the Baltimore Orioles, and batting in all of them. He had 22 at bats, getting 4 hits, for a .182 batting average, with 2 sacrifice hits, 0 sacrifice flies, and 2 runs batted in. He was walked 2 times. He struck out 10 times. He hit 0 doubles, 0 triples, and 1 home run.
10 because 10+10=20 20*0=0 0+10=10
10*10*0 = 0
