In what metric unit is power measured?
The basic metric unit for electrical power measurement is the watt, which is equal to one joule per second.
How does watt and joule relate?
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.
How are watts and joules related?
This is a very good question. A joule is a unit of energy, and a watt is a unit of power. Power is the rate at which energy is converted from potenital to kinetic energy. So power is some quantity of energy divided by some unit of time. In the SI system, a watt is equal to 1 joule per second. Real life example. A 60W lightbulb uses 60 joules of energy every second. Hope this helps!
How dou you convert joules to watts?
Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ.
How joule per kilogram is equal to meter per second?
New answer - J=kg*m^2/s^2. J/kg=m^2/s^2 The definition of Joule is N * m (Newtons times meters) The definition of Newton is kg * m / s2 (kilograms times meters divided by seconds squared) Dividing the unit Joule by kilograms leaves meters per second squared (or meters mer second per second)
What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).
What is the SI unit for power which equals joules per second?
The SI unit for power is the watt (W), which is equivalent to one joule per second (J/s), representing the rate at which energy is transferred or work is done.
What is the metric unit for measuring power?
-- Joule per second-- Watt
How much is one Watt of 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.
How many watts equals 1 joule?
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
Defined as one joule of energy expended over one second of time?
A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.
What is the dimension of time in power?
The unit for power is joule per second, J/s.
Power produced by windmill is 900 Watt Is it per second or per hour?
Watt is a unit of power, not a unit of energy. Joule is the SI unit for energy; Watt means Joule/second. So, the "per time unit" is already implied. Saying "watt per second" or "watt per hour" would be completely wrong. The power is simply "900 Watt".
What is power and what is the unit for power?
Power is the rate at which work is done or energy is transferred. It is measured in watts (W), with one watt equal to one joule per second.
What is the unit of watt?
A watt is a unit of power, and it can also be expressed as one joule of energy per second.
Term for energy per unit time?
Power. One common unit of power is the watt, which is defined as one joule per second.
Is watt a unit of energy?
No, a watt is a unit of power, not energy. Energy is typically measured in watt-hours or joules. A watt is equivalent to one joule of energy per second.
