The cost of electrical energy is computed per energy unit. The more energy you use, the more you will be charged. The unit normally used is the kWh (kilowatt-hour), which is equal to 3,600,000 watt-seconds or joules.The cost per kWh is, at least roughly, determined by supply and demand.
That depends on how long the 1 kW is applied. Please note that kW is a unit of power, not a unit of energy.In general, 1 kW of electrical energy can be converted into 1 kW of heat - if used in a heater. With a heat pump, 1 kW of electrical energy can, in fact, pump several kW of heat energy.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
solar cells are used to change light energy into electrical energy
mechanical energy or chemical energy,radiant energy,and electrical energy
The unit of measurement for electrical energy used in the home is the kilowatt hour, and this is the unit which the electricity supply company uses to work out your bill.
The kWh (kilowatt-hour)
In SI, the same unit is used for any type of energy: the joule.
Power; its SI unit is watt. Please note that this is notspecifically an electrical unit; "power", and the unit "watt", is the rate of energy conversion, and can be used anywhere where energy is converted - whether "work" is involved, or some other (non-mechanical) energy.
Joules(international) or watthours(communly used)
In SI, the same unit is used for any type of energy: the joule.
All forms of energy are measured using the same units. The SI unit for energy is the joule (J). However, the unit used by electrical utility companies is the kilowatt hour (kW.h).
It is the amount in Rs. or Roller which is paid for how much unit of electrical energy consumed. the unit of electrical energy is KW h (kilowatt hour).
The energy used to power a computer is Electrical Energy.
The unit used to represent electrical pressure is VOLTS.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
The unit of measure used to describe electrical "pressure" is the "Volt."
