How many kWh will a 32 watt fluorescent bulb use?
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
How many watt-seconds does a 60 watt bulb use in 10 hours?
You multiply the watts by the seconds. 10 hours is 36,000 seconds, so the watt seconds is 60 x 36,000 Answer 2,160,000 watt-seconds You can also say the bulb uses 60 x 10 or 600 watt-hours.
How many kilowatt hours KWh are used to light a 30 watt light bulb in 8?
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
How many kwh does a 200w light bulb use?
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
What does 40 watts bulb mean?
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.

Watt-hour a light bulb consumes 3600 watt-hours per day How many watt-hours does it consume in 4 days and 6 hours?
-9900
How many kilwatt hours does a 600 watt light bulb use in 18 hours?
0.6 kW times 18 hours = 10.8 kWh.
How much does it cost to burn 7.5 watt night light bulb?
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
How many lumens are in a 1000 watt incondescent light bulb?
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
How can a 60 watt bulb use the same power as a 60 watt bulb can in a second?
Watts is Watts and has no relation to time. w=v*a (west Virginia varsity). A 60 watt light bulb is 60 watts regardless of how long it is on. Watt hours would be what PG&E bills you for.
How much does it cost to run a light bulb?
It depends on the bulb, how many watts it is. All bulbs are marked with the correct voltage and the power taken, in watts. You multiply the watts by the number of hours to find the watt-hours of energy used. Then divide by 1000 to find the kilowatt-hours. A kilowatt-hour is also called a unit and you pay about £0.15 for a unit of electricity. Let's say it's a 100 watt bulb running for 24 hours. That uses 2400 watt-hours or 2.4 kilowatt-hours, which costs about 2.4 x £0.15 which is £0.36.
