By energy you mean watt hours. So the equation is watts x hours = 1680 watt hrs. Or stated in Kilowatts it would be 1.68 kw hrs. Average cost in USA would be about 18 cents.
energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit
from its power if it is 100 watt so it produces 100 joule per second but this includes all energy produced by the lamp (light/heat energy) Their is a formula E=h x v, E=energy, v=frequency, and h=the constant I think
A zero-volt bulb actually runs on some fixed supply voltage, so the term is not strictly correct. The voltage times the current in amps will give the power used by the bulb in watts, which is converted into watt-hours of energy by multiplying by the number of hours used.
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
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

The formula to calculate the energy usage of a light bulb is Power (Watts) x Time (hours) = Energy Used (Watt-hours). For example, a 60-watt light bulb used for 5 hours would consume 300 Watt-hours of energy.

Simple 10,000 hours cause it completes 1 unit in 10 hours.....

60 watt-hrs= 60 watt*1 hr so it will take 1 hour.

Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
The energy given off by a 100 W bulb in 4 hours can be calculated using the formula: Energy = Power x Time. Thus, Energy = 100 W x 4 hours = 400 Wh, or 0.4 kWh.
a fuse bulb is a bulb in which the filament of the bulb burns and it stops working
