How many volts is 200 joules?
How many volts is 200 joules?
Answer and Explanation: A 100-watt light bulb uses 100 joules of energy per second, by definition of a watt. Since there are 60 seconds in a minute and 60 minutes in an hour,…
How many amps is 360 joules?
With high-energy biphasic defibrillators, you need 360 Joules of energy to deliver the maximum current to the heart, approximately 16 Amps in a high-impedance patient.
What is difference between Joule and Watt?
Joule is a unit related to energy or work performed on a system. And watt is a unit of power or the rate in which energy is consumed per unit time.
How many volts is 150 joules?
Kilowatts are equivalent to 1,000 Watts and are the most frequently used unit of electrical power. Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.
How many amps are in a Joule?
Hence 1 kWh is 1,000 times 3,600 = 3,600,000 Joules. So, pulling all this together into an example, suppose you have an appliance which runs at a current of 5 Amps on a 110Volt supply. Then the rate of energy or power being consumed is 5 * 110 = 550 Joules per second, which is 550 Watts or 0.55kW.
How many volts are in a Watt?
Using the power equation of 1 watt = 1 ampere × 1 volt and translating that formula to find volts, you end up with 1 volt = 1 watt ÷ 1 ampere. Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts.
Is joules a unit of power?
Joule is a unit related to energy or work performed on a system. And watt is a unit of power or the rate in which energy is consumed per unit time. Joule is the unit of Energy. Watt is the unit of Power.
Is 1000 joules a lot?
A Joule can be defined in terms of force-distance but it can also be defined as one Watt-second, a Watt applied for one second. … We light it at full power for 10 seconds. That uses 1000 joules or 1 kilojoule of energy. You should have a lot of heat and a lot of light for ten seconds.
How many joules of energy are in one kilowatt hour?
If you use one kilowatt of power for an hour, you have used 1 kilowatt-hour, abbreviated kWh, of energy. One kilowatt-hour is equivalent to the energy of 1,000 joules used for 3,600 seconds or 3.6 million Joules. In equation form: 1 kWh = 3.6 million J.
How many joules does it take to kill you?
Henderson states, according to long established principles, an object which impacts a human is considered 20% chance of being lethal, with a head strike, if its kinetic energy is greater than 80 Joules. 90% chance of being lethal, with a head strike, it its kinetic energy is 150 Joules.
How many joules is 600 watts?
A 100-watt light bulb uses 100 joules of energy per second, by definition of a watt. Since there are 60 seconds in a minute and 60 minutes in an hour,…
What can you do with 1 Joule of energy?
1 joule of energy is equals to 1 watt of electrical energy. WORK: It is said to be work done by a body if a force applied on a body and it covers distance in the direction of force. e.g if we put force to a table it will move in the direction of force greater the force more distance will be covered by the table.
What is 1 watt in joules second?
1 watt (W) = 1.00 joules per second (J/sec)
Are Joules and amps the same?
These are units for different things. Amps (amperes) are a unit of current which is the rate at which charge flows. Joules are a unit of work or energy. Watts are a unit of power which is the rate at which energy is generated or consumed.
What is J equal to?
The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). … The amount of energy delivered by a one watt source of power in one second is one Joule.
How many joules are in a lightning strike?
The energy of an average 3 mile-long lightning strike is one billion to ten billion joules. To keep a 100-watt light bulb going for one second, one hundred joules of energy will be used. With one billion joules, the light bulb will be lit for 116 days.
What does 1000 joules mean?
A unit with up to 1000 joules of surge protection is adequate for these small electronics. … A surge protector with 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers.
How many joules does the average house use?
11,000 hours is 11,000 x 3,600 seconds which is 396,000,000. Multiply and get about 396,000,000 joules a year. divide this by 365 and get a little over a mega joule a day.
How do you calculate joules from Watts and time?
To determine the joules of energy exerted substitute the watts and time in seconds in the formula and solve. Joules are equal to the power in watts times the time in seconds. For example, find joules of energy for 50 watts of power over 25 seconds.
