what is the difference between electrical energy and electrical power?
444556
The fundamental difference between electrical energy and electrical power is that electrical energy represents the amount of work done that causes electric current to flow through a circuit. As against electrical power defines the rate at which work (basically movement of charges) is done in an electrical circuit.

The major difference between the electrical and electronic devices is that the electrical devices convert the electrical energy into the other form of energy like heat, light, sound, etc. whereas the electronic device controls the flow of electrons for performing the particular task.

Electrical energy is energy that is caused by moving electric charges. ... The faster the electric charges are moving the more electrical energy they carry. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.

Electricity has more to do with electronic currents and fields, while magnetism focuses more on fields and currents of a magnetic nature. Electricity is typically described as a force that occurs during the presence of electric charges. These forces take place due to shifts in electric charges.

The mechanical power is measured by the rate at which work is done. ... The unit Kw is an electrical as well as mechanical power unit. Though the basic concepts remain the same, the form of the governing equations in case of the mechanical power is different than that of electrical power.

The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical.

A mechanical device may be rated by its horsepower. But there is an equivalency between mechanical power and electrical power and the units may be converted; 1 HP = 746 watts. Note, however, there is difference between power and energy. Power is the rate of doing work while energy is the total work done.

The energy trapped inside each atom. Electricity is the FLOW of energy from one place to another. Nuclear energy can actually be used to make electricity. An atomic chain reaction is controlled to produce heat to boil water. The resulting steam turns a turbine and a generator and makes electricity.

What is the difference between electric force and electric energy? It's the same as the difference between force and energy in any other context. ... The energy provided is then the force times the distance moved.

Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field. Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.

An electric motor is a machine that converts electrical energy to mechanical energy. An electric generator is a machine that converts mechanical energy to electrical energy. ... The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field.

Electrical power is the rate of amount of electrical energy transferred. Electrical energy is the energy generated as the result of the potential difference in a circuit which causes current to flow through it. ... Electrical energy is usually measured in KWH(kilo-watt-hours).

The main difference between electrical and electronic circuits is that electrical circuits have no decision making (processing) capability, whilst electronic circuits do. An electric circuit simply powers machines with electricity.

It can be measured by the change in energy. Energy is capacity of doing work. For example if a something has energy of x joule it can perform x joules of work. Power is the work done in a particular unit of time e.g. one minute.

Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word "electricity" is sometimes used to mean "electrical energy".

Nuclear, potential and chemical energies implies the stored form of energy. But electrical energy is not a form of stored energy.
