How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
What is energy measured by?
Energy is measured in Joules in the SI system. Thermal energy can be measured in calories (1 calorie = 4.2 Joules) or BTU. In traditional units, energy is in ft.lbforce! energy is measured in calories and use to be measured in joules
What is the relationship between time and energy consumption?
Assuming a constant power:(energy consumption) = power x time In SI units: joules = watt x seconds Of course, if the power is not constant, you need to replace the formula by an integral.
How many joules does a 800 watt toaster consume in 2 minutes?
Energy = power X time. 800W X 120sec = 96000J
How much power per year does a 1.5mw wind turbine generate?
The power of a 150-megawatt wind turbine is 150 megawatts,or 150 million watts.The energy it generates is 150 million joules per second, or 150 thousand kilowatt-hours per hour.1 day = 86,400 seconds1 year = 365 days (rounded)150 million joules per second = (150 million x 86,400) joules per day =(150 million x 86,400 x 365) joules per year =4.7304 x 1015 joulesof energy per year (4,730,400,000,000,000 joules of energy per year)If we convert this number to the more familiar unit that appearson your electric bill, it's equal to1,314 million Kilowatt-hours of energy per year
What is the average power requirement for the US in watts if the total annual U.S. energy consumption is about 2 x 10 to 20th power joules (1 watt is 1 joules)?
Watts = joules / secondYou need to divide the total annual energy consumption by the number of seconds in a year (which is about 31.5 million).
How much power in watts will an led bulb consume if its energy is 6 joules?
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.
What unit measures electrical energy consumption?
In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules.
How much electricity does the world a year?
The annual global energy consumption is estimated to 580 million terajoules. That’s 580 million trillion joules or about 13865 million tons of oil equivalents. (mtoe). Since 2000, global energy consumption has increased by about a third and is projected to continue to grow in the foreseeable future.
How much electricity does the world use a year?
The annual global energy consumption is estimated to 580 million terajoules. That’s 580 million trillion joules or about 13865 million tons of oil equivalents. (mtoe). Since 2000, global energy consumption has increased by about a third and is projected to continue to grow in the foreseeable future.
What are the patterns of energy consumption?
Energy consumption patterns are based on the economy of a specific country. If you consume large amounts of energy you need to find ways how to conserve and get energy that can be substituted for it.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
The amount of energy used when you consume one kilo-watt in one hour?
One kilowatt-hour, or KWH.Additional AnswerYou don't 'consume power'; you consume energy. Power is a measure of the rate at which you consume energy.
What is energy measured by?
Energy is measured in Joules in the SI system. Thermal energy can be measured in calories (1 calorie = 4.2 Joules) or BTU. In traditional units, energy is in ft.lbforce! energy is measured in calories and use to be measured in joules
What is the relationship between time and energy consumption?
Assuming a constant power:(energy consumption) = power x time In SI units: joules = watt x seconds Of course, if the power is not constant, you need to replace the formula by an integral.
What are bigger units of works?
Well since Joule is the standard unit a Megajoule (1 million joules) or a kilojoule (1000 joules) can be used. Also a kilowatt-hour (3.6 million joules) is used by electric companies to keep track of the energy people use.
Do Canadians consume about seven thousand cans of energy drink every year?
no. Canadians consume about seven million cans of energy drinks every month.
