Calculate number of joules in 1kwh?
1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
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.?
To calculate this, we first need to convert the energy from joules to watt-hours. 90 joules is equal to 0.025 watt-hours. Therefore, with 0.025 watt-hours of energy, a 40 watt light bulb would last for approximately 0.000625 hours or 0.0375 minutes.
How much work does a 100-watt light bulb do when its lit for 30 seconds?
3000 joules(J)
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
How many joules are in 746 watt-seconds?
1 watt-second = 1 joule...746 watt-seconds = 746 joules(746 watts is an interesting number, and I'm curious to know how it wasselected to be the number in the question. 746 watts = 1 horsepower.1 horsepower = 746 joules of energy per second.The number is easy to remember: The mainsail on the Santa Maria developed2 HP in a fresh breeze during Christopher Columbus' first voyage in 1492.)
Another word for joules?
newton-meters watt-seconds
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).
How many joules does a 40 watt ight bulb convert in 10 seconds?
Four Hundred Joules
How much energy does a 95 watt light bulb use in 40 seconds?
The energy is 95 x 40 watt-seconds (Joules).
What is the label for work?
Work is measured in joules or in watt-seconds, or equivalent units.
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.
Calculate number of joules in 1kwh?
1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
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 do I convert Watt seconds to milliwatts seconds?
To convert Watt seconds to milliwatt seconds, you can multiply the value in Watt seconds by 1000. This is because 1 Watt is equal to 1000 milliwatts. So, 1 Watt second is equal to 1000 milliwatt seconds.
Convert Watt seconds to milliwatts seconds?
To convert Watt seconds to milliwatts seconds, you need to multiply by 1000 since there are 1000 milliwatts in a Watt. For example, if you have 5 Watt seconds, it would be equal to 5000 milliwatts seconds.
How long could 90 Js of energy light a 40 Watt light balb.?
To calculate this, we first need to convert the energy from joules to watt-hours. 90 joules is equal to 0.025 watt-hours. Therefore, with 0.025 watt-hours of energy, a 40 watt light bulb would last for approximately 0.000625 hours or 0.0375 minutes.
