What is the formula of power?
Power Formula 2 – Mechanical power equation: Power P = E ⁄ t where power P is in watts, Power P = work / time (W ⁄ t).
Energy E is in joules, and time t is in seconds..
How is power calculated?
Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
How many volts are in a Watt?
Converting the Wattage 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.
What is the unit of Joule?
What is the smallest unit of power *?
Joule is the smallest unit of energy. But for some bigger calculation, some better unit is required. So, the unit used for electrical energy is watt-hour. Watts are the basic unit of power in which electrical power is measured or we can say that rate at which electric current is being used at a particular moment.
What is the smallest and largest unit of charge?
The SI unit of charge is Coulomb. Charge can also be represented by Ampere-hour. In chemistry, charge is represented by unit Faraday. However the largest unit of charge is Coulomb where 1 Coulomb = Faraday.
Which unit is Watt?
A watt is a unit of power. A watt (W) is a joule (J) of energy used or produced per second. In 2010, the average US power use was 3.3 terawatts, or 3,300,000,000,000 watts. A horsepower is a unit of power.
What is the unit of power?
How many volts are there in one unit?
So to display the units or multiples of units for either Resistance, Current or Voltage we would use as an example: 1kV = 1 kilo-volt – which is equal to 1,000 Volts. 1mA = 1 milli-amp – which is equal to one thousandths (1/1000) of an Ampere.
What happens to the body on which work is done?
Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to the motion of the object, the work is considered to be negative, implying that energy is taken from the object.
What can a gigajoule power?
One GJ is equal to 277.8 kilowatt hours ( kWh ), 1.055 million British thermal units ( Btu ) or 0.17 barrels of oil. Burning 1 million wooden matches completely at one time releases one GJ of energy. … A GJ can measure energy from various types of power, such as electricity, natural gas and oil.
What is a power in math?
An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor. 31.
