Electrical energy is a form of energy resulting from the movement of charged particles, such as electrons, through a conductor. It is commonly used to power devices and appliances in our daily lives.
The formula for calculating electrical energy is E = P x t, where E is the energy in joules, P is the power in watts, and t is the time in seconds. For example, if a device uses 100 watts of power for 2 hours, the electrical energy consumed would be 200 joules.
The unit for electrical energy is the joule, which is equivalent to one watt-second. However, in practical applications, electrical energy is often measured in kilowatt-hours (kWh) for larger amounts of energy.
Electrical energy is the total amount of energy consumed or produced, while electrical power is the rate at which energy is used or produced. In other words, electrical energy is a measurement of the total amount of work done, while electrical power is a measurement of the rate at which the work is done.
Some common examples of devices and appliances that use electrical energy include light bulbs, refrigerators, televisions, computers, and smartphones. Power plants also produce electrical energy to power homes and businesses.
