In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules.
A unit (short for 'Board of Trade Unit') is used to measure energy consumption, and is equivalent to one kilowatt hour. A watt measures power, which is the rate of energy consumption. So there is no relationship between a unit and a watt.
The researcher likely used a device called an energy meter or wattmeter to measure the electrical energy entering the toaster. This device measures the power consumption of the toaster over a period of time, which can then be used to calculate the total energy consumption. The unit of electrical energy is typically measured in kilowatt-hours (kWh).
Quantity of electrical energy.
In SI, the same unit is used for any type of energy: the joule.
The word you're looking for is "watt." A watt is a unit of power that measures how fast electrical energy is used.
if power consumption is 130 KW. how can it convert into unit per hour.
In SI, the same unit is used for any type of energy: the joule.
kilowatt-hour (kWh)
The unit to measure the amount of electrical energy is the kilowatt-hour (kWh). It is commonly used by utility companies to bill customers for electricity consumption.
One energy unit starting with C is a calorie, which is a unit of energy commonly used in nutrition to measure the energy content of food. Another energy unit is a coulomb, which measures electrical charge.
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
