The term 'unit' is short for the obsolete expression, 'Board of Trade Unit', and is used by British utility companies to measure the consumption of electrical energy by their consumers. An 'unit' is exactly equivalent to a kilowatt hour.
A 'watt', in the other hand, is the unit for power - which is the rate at which energy is consumed. Domestic consumers are not charged for their rate of consumption.
So an unit is equivalent to one kilowatt hour - there is no relationship between an unit and a watt.
Your question demonstrates why it is important to write symbols correctly!!! A lower-case 'm' represents 'milli' (one thousandth); a lower-case 'w' doesn't stand for anything -although, you probably think it means 'watts', which it doesn't!
Presumably, therefore, you either mean 'mW' or 'MW'. The symbol, 'mW', represents a 'milliwatt' (one-thousandth of a watt), whereas the symbol 'MW' represents a 'megawatt' (one-million watts).
As you can see, there is a huge difference -so you must learn to write your symbols properly!
A watt is a watt of course. You can't do anything to get one! It's just a measurement of power in a electrical source
one KW usage for one hour is eaqual to one KWh, commonly said as unit.
if you use one kW continuously for an hour, your electric energy meter will register 1 KWh = 1unit.
Is equal to one joule per second of work done according the SI unit system
A watt is NOT a unit of electrical energy (or of any type of energy). A watt is a unit of power (energy per time unit), and it's equal to one joule per second.
1,000 watts? 0.001 megawatts?
One joule per second
That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.
The Watt is the unit for power in the SI system, defined as 1 Joule per second. A Joule is the work done in moving 1 meter against a force of 1 Newton. If you are not familiar with the metric system, you may like to know that 1 kilowatt (1000 watts) is equal to 1.341 horsepower. In electrical work the Watt is (volts x amps), that is the same quantity as 1 Joule/sec, which makes it easy in the metric system to work with mechanical and electrical quantities at the same time.
You cannot, unless your first "h" (in amph), is a msitake. If you really mean, convert Whr into Ahr, then you need to divide the Whr figure by the voltage.AnswerYou don't! A watt hour measures energy, whereas an ampere hour measures charge -two different quantities!
1 joule per second is 1 watt. So 1 million joules per second is 1 million watts, or 1 Megawatt.
You gave no examples to choose from. Power is Energy divided by time. P = E/t In the metric system, the unit of power is the Watt. One Watt is one Joule per second, energy divided by time, 1 J/s. Power is the rate of change of energy.
The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second.
An abwatt is a unit of electrical power equal to one ten-millionth of a watt.
One kilo hour equals to one hour. This is used in energy.
Power is always the time-rate of energy, i.e. the rate of change (or transfer) of energy with respect to time.If Energy is measured in Joules, then one Joule being transferred in one second is equal to one Watt of power.Electrical power is the time rate of change of electrical energy, P=dE/dt.Power = energy / timeIt usually referst to some type of energy transfer. In SI units:Watts = joules / second
The watt is a unit of measurement as related to electrical energy. eg: one (1) kilowatt hour equals 3,412 BTUs.Another AnswerEnergy is not measured in watts, but in joules. A watt is used to measure power.
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.
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
Volts is not a measure of energy so there is no way to have 18volts of energy. Energy is measured in Joules, or sometimes calories. Watts is a measure of energy transferred per second. In electrical terms, 1 Watt is equal to 1 Volt at a current of 1 Amp. In one second, 1 Watt will transfer 1 Joule of energy.
kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.
A unit (short for 'Board of Trade Unit') is used to measure energy consumption, and is equivalent to one kilowatt hour. A watt measures power, which is the rate of energy consumption. So there is no relationship between a unit and a watt.
One gallon of power is approximately 8.3 pounds, so the energy released, when 1 gallon of water falls 10 feet, is 83 foot-pounds, which is equal to 0.31 watt-hrs. If this energy were mechanically converted to electrical energy, approximately 40% losses would occur in converting the falling water into rotational, mechanical energy by a Pelton wheel or other water impeller, and about a 5% loss in conversion of rotational energy to electrical energy by a generator. So the extracted energy would be about 50%. Of that 0.31 watt-hours of energy, about 0.15 watt-hours would be delivered in the form of electrical energy, and the other 0.15 watt-hours would be lost in the form of heat.
