What SI unit is used to express power?
the answer for the si unit of power is the watt or w
What is 1 watt of power?
One Watt is one Joule of energy transfered every second. So the Watt is the unit of enegery transfer.
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The unit watt is defined as energy per unit time. Thus a 100W light bulb consumes 100J of energy each second. Joules are a unit of energy. Watts are a unit of power.
What is the unit used for the measurement of power?
Using Energy miter.... It is called a WATT from the inventor James Watt.
How many watts are in a liter?
None, these are two different units of measurement. A liter is a unit of volume, a watt is a unit of energy. A watt is a unit of power. One watt is one joule per second, that is watts measure energy used over a period of time.
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.
Is a watt a unit of power or a unit of electrical energy?
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
How how does watt to energy work?
Watt is a unit of power. watt hours is a unit of energy. (Note x watts times y hours is what you pay for on your electric bill.)
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.
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.

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".
A unit of energy is the unit of what?
... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.
How do you convert Whr to W?
the question is a bit stupid...W-hr (Watt hour) is unit of Energy while W (Watt) is unit of Power.So dividing energy (in Watt-hour) by time (in hours) will give you Watt.Power = Energy / Time
What is a unit to measure the amount of electrical energy?
a watt
