Explain How Electrical Power And Electrical Energy Are Related

The rate at which the work is being done in an electrical circuit is called an electric power.

Explain how electrical power and electrical energy are related. Provide appropriate definitions for the following electrical terms. Electric power like mechanical power is the rate of doing work measured in watts and represented by the letter p the term wattage is used colloquially to mean electric power in watts the electric power in watts produced by an electric current i consisting of a charge of q coulombs every t seconds passing through an electric potential difference of v is. Ans electric power measure of the rate of electrical energy transfer by an electric circuit per unit time. The si unit of electric power is watt.

In other words the electric power is defined as the rate of the transferred of energy. Radiant energy is energy related to radiation. Electron electric charge electric potential resistance current power conductor semiconductor and insulator. In this case it is the electrical attraction between the atoms a potential energy is energy related to some conservative force.

Students will be able to. This energy is supplied by the combination of electric current and electric potential that is delivered by an electrical circuit e g provided by an electric power utility. Any electrical appliance needs to be given enough energy every second. When calculating the real power consumption of an electrical device it is essential to measure the voltage applied and the current consumed taking into account the power that is dissipated in the circuit.

Electrical energy vs electrical power. Electrical energy is energy derived from electric potential energy or kinetic energy when used loosely electrical energy refers to energy that has been converted from electric potential energy. Electrical power can be delivered as a low current with a high voltage. Electric energy on the other hand is energy related to electricity such as electrical currents and stored charges.

The electric power is produced by the generator and can also be supplied by the electrical batteries. A potential energy is energy related to some conservative force. Write the electric power formula and explain the terms. Write the si unit of electric power.

Energy can be transferred by an electrical current. Since power is energy per unit of time in theory it can be calculated after measuring the energy used per second. Electric energy and electric power are two very important quantities in electricity and electronics.
