The amount of power needed to do 10 joules of work in 1 second is?
10 joules per second = 10 watts
The power of a light bulb that converts electrical energy at a rate of one hundred joules per second is?
1 joule is the energy equal to 1 watt for 1 second.100 joules = 100w for 1 second.A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.Only about 1% of this is useful light, the rest is wasted as heat.AnswerPower is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W.
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
100 joules/second = 100 watts.
What is the power output of a candle?
26.25 Joules per second
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.
What is the energy used in one second when a bulb have 40Watts.?
40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second...
What is the time taken by a body to perform 440 Joules of work at rate of 11 watt?
11 watts = 11 joules per second(440 joules) / (11 joules per second) = 40 seconds
How many units per hour utilized by a 45kw motor?
watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.
What is the difference between voltage and power?
Voltage is electromotive force, in joules per coulomb. Power is energy transfer rate in joules per second, also known as watts.Not asked, but answered for completeness sake, and also to show the relationship between voltage and power, current is charge transfer rate in coulombs per second. So, if you multiply voltage (joules per coulomb) by amperes (joules per second) you get watts (joules per second).
Will the value of joules constant be same if AC were used instead of DC?
Joules measure energy (power x time). If the AC voltage is expressed as rms (root mean square) and not peak, and there are no capacitors or inductors in the circuit, then the joules per second (=power ) will be the same.
Electric power is defined as?
Power is joules per second, also known as watts. You can calculate watts if you know volts and amperes by simply multiplying them together, because volts is joules per coulomb and amperes is coulombs per second - multiplying them gives you joules per second. It gets a little complex when you start talking about AC power, because current and voltage is not always in phase, but the principle is the same.AnswerThere is no such thing as 'electric' power. Power is not a 'thing', it's a rate: the rate of doing work, or of heat transfer, expressed (as explained above) in joules per second which has been given the special name, the watt.
What is the amount of power needed to do 10 joules of work in 1 second?
10 joules per second = 10 watts
The amount of power needed to do 10 joules of work in 1 second is?
10 joules per second = 10 watts
What is 5 kilowatts in joules per second?
1 watt = 1 joule per second1 kilowatt = 1,000 watts5 kilowatts = 5,000 watts = 5,000 joules per second
10 kw equals how many joule per second?
10,000 joules per second.
How to calculate rate of energy transfer in Joules per second or Joules per minute?
You can divide any unit of energy by any unit of time; but the standard SI unit is Joules / second, and has the special name "Watt".

Therefore, 100 J/s is exactly equivalent to 100 W.
