It is also equal to one watt of power emitted or dissipated for one second, or watt second (Ws). In various applications, British thermal units (BTU) are used to express the unit for energy. One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (...

A watt is a minuscule unit of measure, so when discussing large-scale energy consumption like in homes which need thousands and even millions of watts – it’s much more understandable to use bigger units such as kilowatts (1kW = 1,000 W) or megawatts (1MW= 1,000 kW). Your electricity...
What is 3 joules in fps? (a) How much more electrical energy is produced by the more efficient power station? (b) How much less heat transfer occurs to the environment by the more efficient power station? What is the equivalent of 1 kWh in Joule?
How many amperes flow through a 60 watt bulb when 120 volts are impressed across it? Convert joules to kilowatt hours The power rating of a lightbulb is 55W when running in a 120V circuit. a) Find the current in the bulb. b) Find the bulb's resistance....
A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on. What is a giga watt? Gigawatt hours, abbreviated as GWh, is a unit...
burn gasoline under ideal conditions, with plenty of oxygen, you get carbon dioxide (from the carbon atoms in gasoline), water (from the hydrogen atoms) and lots of heat. A gallon of gasoline contains about 132x106joules ofenergy, which is equivalent to 125,000 BTU or 36,650 watt-hours...
as,1 Atm = 101325 pascals, while1 dyn/cm2 = 0.1 pascals. thank you. What is the unit of power? Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power isthe watt (W), in honor of Scot...
In physics, electric power is the rate of doing work. It is equivalent to the amount of energy consumed per unit of time. The unit for power is Joule per second (J/s), also known as Watt (W). What is electrical power Electrical power is the rate per unit of time that electrical ...
Joule, in terms of electricity, is equal to the energy transferred when one coulomb of charge passes through a potential difference of one volt. The circuit's energy output was measured to be 150 joules. 4 Watt Watt, in electrical terms, is the power developed when one volt of potential ...
