60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
How long could 90 Js of energy light a 40 Watt light balb.?
Power (watts) = Energy (joules) / time (seconds). Thus, Time (seconds) = Energy (joules) / Power (watts) = 90J / 40W = 2.25s
What is the watts equivalent of 231000 joules?
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
Write a relation between commercial unit of electricity and the SI unit of energy?
1 kWh = 3,600,000 joules (or watt-seconds).
How much time is required for an operating 75 watt light bulb to dissipate 10 joules of energy?
1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds
How much energy does a 95 watt light bulb use in 40 seconds?
The energy is 95 x 40 watt-seconds (Joules).
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).

A 60 watt light bulb runs for 5 seconds how much energy does it use?
That would be 40x60 watt-seconds, also known as Joules, so it's 2400 Joules of energy. 3.6 MegaJoules is equal to one kilowatt-hour, also known as 1 unit.
How many joules of energy are in 1 kWH?
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
How many watts per hour to equal 1000 btu's?
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

How many joules are needed to run a 60 watt light bulb for 1 minute?
1 Watt means 1 Joule per second, so 60 watts means 60 Joules per second. A light bulb that burns energy at that rate for 3 seconds uses 180 Joules.
How much power is used when 600J of work are done in 10s?
60 W
What is energy-consumed when power240watt and time10hrs?
Convert the hours to seconds. 1 watt is 1 joule/second, so the energy (in joules) is simply the power (in watts) x the time (in seconds).
Another word for joules?
newton-meters watt-seconds
