1 watt hour equals how many watts?
1 watt-hour equals 1 watt times 1 hour, or 3600 joules.
How much energy does it take to light a 60-watt light bulb for an hour?
Actually, your wrong. Sure, the lighting ithat is set for proper illumination is 60watts, but if anyone is used to using a dimmer, you can dial down the power consumption for a typical incandescent bulb and it will still light. And as expected, the light level will decrease as you lower the dimmer setting as well.
How much energy does a 1000 watt light bulb use per hour?
A 60 watt light bulb uses 60 watts of power in a period of one hour or 60 watts in one minute or 60 watts in one second or 60 watts during any period of time.How much total energy a 60 watt light bulb "consumes", which is the amount of electricity that has to be paid-for, is measured in watt•hours (that's watts times hours). So a 60 watt bulb consumes 60 watt•hours in one hour, or 60 Wh x 24 hr/day = 1440 Wh per day.That is the same as 1.44 kilowatt•hours (kWh), so, if you look up what your electricity supplier charges for 1 kWh you can figure out how much it would cost you in money. If 1 kWh costs you 25 cents, then leaving a 60 watt light bulb switched on for 24 hours straight would cost you 1.44 kWh x 25¢/kWh = 36 cents.
How much a hour does 100 watt bulb use at 15p?
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
How much work is done using a 60-watt light bulb for 1 hour?
In terms of joules, the answer is 216,000 joules. First, you must convert 1 hour to seconds. 1 hr = 60 mins 60 mins = 3,600 seconds The formula for finding power can also be used to find work if power and time are provided. Power = Work/Time 60 watts =work/3,600 seconds To find this, multiply 3,600 by 60 3,600 X 60 = 216,000 The unit for work is joules, so the answer is 216,000 joules.use the power formula
1 watt hour equals how many watts?
1 watt-hour equals 1 watt times 1 hour, or 3600 joules.
How much does it cost to run a 1000 watt light?
About 7 cents an hour.
How much does a 150 watt light bulb use per hour?

How many kilowatts per hour produce 10 MW?
MW is a unit of power just like kW 1MW = 1000 kW 1 mega-watt = 1000 kilo-watt Watt is a measurement of power. watt-hour is a unit of energy 1 mega-watt-hour = 1000 kilo-watt-hour
Is a watt a light bulb?
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
The rate which electrucal energy does work?
I believe you are thinking of a watt perr hour or more commonly used is a kilo-watt-hour - that's the amount of power used in an hour, not exactly how much work is done however.
What does output watts per hour mean?
This has no physical meaning. The correct unit for power is the watt (not watt per hour).
How much money do you save per year when you swith from 60 watt light bulb to 40 watt?
It depends on how much you use the light, and how much power costs in your area. You can find out the second by looking at your electric bill... it'll give the cost per kWh (kilowatt-hour). The difference between a 40 watt bulb and a 60 watt bulb is 20 watts, meaning you'd have to leave the light on for about two days straight for the savings to be even one kilowatt-hour, and if it were on all the time in a year you'd save 180 kWh or so... almost certainly less than $20.
How many watts do light-bulbs use per hour?
Your question is rather like asking, 'How many miles per hour do you do in one hour?' A watt is simply the rate at which you use energy or do work, and it is the same regardless of over what period it is measured.
How much energy does a 1000 watt light bulb use per hour?
