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
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 60 Watt light bulb consumes electrical energy. If you leave is on for 24 hours, it consumes 60 x 24 = 1440 Watt-Hours, or 1.44 Kilowatt-Hours. If you want to know how much money this much energy costs, look on your last electricity bill. There it will give the cost of one Kilowatt-Hour.
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
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

the second bulb become weak because there's not a lot of energy being transformed into bulb 2
A 60 Watt light bulb consumes electrical energy. If you leave is on for 24 hours, it consumes 60 x 24 = 1440 Watt-Hours, or 1.44 Kilowatt-Hours. If you want to know how much money this much energy costs, look on your last electricity bill. There it will give the cost of one Kilowatt-Hour.
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.
This would be 30 watthours, or 0.030 kilowatthours
a fuse bulb is a bulb in which the filament of the bulb burns and it stops working
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
Suppose you a regular 100 W bulb that is replaced by a 20 W energy saving one, that saves 80 W. If it's a bulb that is on 6 hours a day it would use 876 units per year, while the energy saving bulb would use one fifth of that, 175 units. The saving is 701 units that would cost about £100. The energy saving bulb also lasts longer, 8000 hours instead of 1000 hours. In the above example the 100 W bulb would need to be replaced twice, while the energy saving bulb lasts 8000 hours, that would be nearly four years (on average).
A 0 Watt bulb does not consume electric power so the cost is zero.
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
