3500W, or 3.5kW
Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts.
ive only been on an electrical installations course for 2 days, but basically the earth cable does nothing.its a safety feature, so that any fault which happens in a wired system, will be taken by this cable straight to the ground, instead of to you, so this earth cable needs to be completely fit, and properly fit to every electrical component.
calulate the voltage of a battery that provides 20 joules of energy to every 5 coulombs of charge
The length of the cable is determined by the distance from the center of the distribution panel to the center of the load.
every 2 years, the cables are changed.
2008 NEC Section 358.30 requires EMT to be securely fastened every 10'.
Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.
"59.4 watts" means "59.4 joules every second"
600
You decide that for yourself, whether you consider it small or large. To give you an idea, watt means joules/second, so a 40-watt light bulb uses 40 joules every second.
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.
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.
Energy / time is known as power. In SI units, time is measured in seconds, energy in joules; the unit for joules / second has the special name watts.
In the sense of 'work' as force moving through a distance, a light bulb does none of that. But in the sense that mechanical work is equivalent to energy in other realms, the 75-watt light bulb consumes 75 joules of electrical energy every second, and radiates 75 joules per second of energy in the form of light and heat.
1000 joules every second
"kilowatts" is a rate, not a time. A kilowatt is 1000 watts, or energy being transferred at 1000 joules per second. (A watt is a joule per second.) Your question means the same as this question: "What is the measurement in time for 100 forty-watt lightbulbs?" You can leave the lights on as long as you wish. Collectively, every second they will convert 4000 joules of electrical energy to light and heat energy.
3 Kilowatts is a measure of electrical power and means the wind turbine produces 3,000 joules per second. So the question is fairly meaningless, assuming the wind is at the right speed it will be producing 3kW every second, every hour and every day!
Horsepower = (number of joules of energy every second) divided by (746).
