Exemplary Unit Of Watts
Kilowatt-hour is a unit of energy.
Unit of watts. Watt is the unit of power. A joule is a unit of work also known as force acting over a distance ie F d. In 2010 the average US power use was 33 terawatts or 3300000000000 watts.
Power in watts is the rate at which energy is consumed or generated. Watts are basically the miles-per-hour measurement of the electrical world--they tell you how fast the electrons are speeding down the highway. 1 BTU is defined as the amount of heat required to raise the.
Watt W is a joule J of energy used or produced per second. The power P in watts W is equal to the voltage V in volts V times the current I in amps A. Power measures the rate of energy conversion or the rate at which work is done.
The voltage V in volts V is equal to the square root of the power P in watts W times the resistance R in ohms Ω. The symbol for a watt is W. BTU British Thermal Unit is a unit of heat.
In the International System of Units SI the unit of power is the watt W which is equal to one joule per second. In an electrical system power P is equal to the voltage multiplied by the current. Some devices require only a few Watts to operate and other devices require larger amounts.
And acceleration is an exponential increase in distance over time ie ds2. The reason watts matter is because you can improve energy efficiency if you understand them. A watt is a unit of power equal to one joule per second.
