What does "transformation of Electrical energy" means?

The easiest example would be to turn on a electrical pump motor. By toggling the switch, it sends electrical current to the motor. This causes the motor to turn, which changes the electrical energy to mechanical energy and then turns the pump, which will then move fluid (Hydraulic Energy).

Power electronics is the technology associated with the efficient conversion, control and conditioning of electric power by static means from its available input form into the desired electrical output form.

Another way of getting electrical energy for a laptop is using a dynamo machine transforming mechanical rotation into electric current.

Electricity generated by relative motion of a magnetic field and an electric charge.\nMaxwell's 2nd equation states that a magnetic field that varies at a given point induces an electric field that exerts a force on an electric charge.  This force moves the charge.  The free electrons in a conductor are such a charge, and are moved by the relative motion of the conductor and the magnetic field.  \nGenerators and transformers are common applications of this effect.  In a generator the magnetic field may be intrinsically constant (created by DC or a permanent magnet), or varying (created by AC).  The conductor is a coil or set of coils.  No mechanical relative motion of the field and conductor is needed if the field is intrinsically varying.  If such relative motion is needed, the coil can be rotated with the magnetic field held stationary or vice versa, so relative motion of the conductor and the magnetic field occur.  \nIn a transformer the current is always AC and no mechanical motion is needed.  The magnetic field is produced by an input coil (an electromagnet), which shares its core with the output coil for good magnetic field coupling.

No way.  And the evidence is easy to find, too.  Plug in a power converter and run something off it for a while, then put your hand on the converter -- it's hot, right?\n\nThat heat is *wasted energy* -- converting electricity from one voltage to another requires work to be done, and that work generates heat, which is the indication of the inherent inefficiences of the process.  If you then reconvert the electricity to 120V, you will experience a second inefficiency, evidenced as more heat lost.

Okay.  Well, usually it's like this:\n\n1. The first energy transfer depends on the kind of power plant, but the principle is a Fuel->Heat/Kinetic energy transfer.  In a nuclear power plant, the first transfer is Nuclear->Heat, in a coal plant, Chemical->Heat, etc.\n\n2. This heat from the initial reaction is used to boil water.  The energy remains in the form of Heat/Kinetic energy, but is simply transferred to the water.\n\n3. The steam turns a turbine.  Still kinetic energy.\n\n4. The turbine creates an electric potential.  Kinetic->Electric transfer.\n\nTo sum up: fuel reacts, boils water, steam turns turbine, turbine makes electricity.  Chemical/Nuclear/what-have-you -> Heat/Kinetic(in the water) -> Kinetic(the turning turbine) -> Electric

A generator is a machine that converts mechanical power to electrical power, by making a conductor cut across a magnetic field's lines of force.  This is done by moving either the conductor or the magnetic field.  Current flows in the conductor if its ends are connected to an electrical load thus producing electrical power.  Because an opposing magnetic field is created by the current in the conductor, it requires mechanical energy to maintain this motion.

Electricity is a form of energy.\n\nIt can be generated from other forms of energy, for example, chemical energy (burning fuel, or a battery), mechanical energy (a windmill), nuclear energy (atomic fission reaction like in a power plant).\n\nIn a battery electrical energy is converted from the  potential energy stored in chemicals which is released when they combine.\n\nIn a fuel cell, chemical energy is released in another type of chemical reaction.\n\nNuclear plants, windmills, hydroelectric dams or burning fuel in a generator turns a turbine or motor which moves a coil of wire through a magnetic field which produces energy.\n\nIn thermoelectric energy, heat is turned into electricity when two different metals are heated.

The same as making pizza and delivering it.\n\nMaking pizza= converting\nYou change electricity to mechanical energy\n\nTransmitting is sending enery to another point or delivering to pizza.

hey men first know wat is a turbine.\nA turbine is a prime-mover used to provide the mechanical energy required for the generator.\nPrinciple of generators:\nwhenever a flux linking in a conductor changes there is an emf induced in the conductor.\n\nhere the flux is provided initially by a battery or some electrical source and the mechanical energy is provided by the turbine.\n\nIf u see the Mechnical energy from the turbine is converted into electrical.\nRemember energy can be converted from one form to another.This is the basic law.

Consider a system of charges. The charges of the system exert electric forces on each other.If the position of one or more charge is changed, work may be done by these electric forces.We define change in electric potential energy of the system as negative of the work done by the electric forces as configuration of the system changes. Potential energy of the charge particle in an electric field depends on the magnitude of the charge.However, potential energy per unit charge has a unique value at any point in an electric field.For eg. We place a positive charge x Coulomb at a point in an electric field where particle has an electric potential energy of y Joule. Then potential energy per unit charge is =x/y J/C(Using unitary method)\nIf we replace our charge by another charge of magnitude 2x Coulomb.We would find that the second charge has a potential energy of 2y Joule.Potential energy per unit charge would be same.Potential energy per unit charge is independent of the charge we are using.\nThe potential energy per unit charge at a single point in an electric field is called the Electric Potential.Now the difference between the Electric Potential between two points is called Potential Difference between those two points.\nPotential difference is directly proportional to current.(Ohm’s Law)\n\nFor further queries e-mail me:  trust_amplifier@yahoo.com

Energy comes in many forms, right? Electrical, kinetic, potential, heat, chemical etc. And energy can be converted between these forms right? i.e. when you drop something from a height, potential energy is converted into kinetic energy. Same thing when you release a compressed spring. \n\nThe quality of energy refers to the ease with which you can harness it for use and conversion to other forms. For example the energy stored in a battery is high quality energy, since it's easy to harness for use. The ambient heat energy in a room, on the otherhand, is low quality energy, since it not easy or practical to extract the energy for use.

Props to mathematician.  To expand, a "machine" must transform energy in some way.  The second law of thermodynamics describes that any time energy is transformed, entropy is created.  Whenever entropy is created, the "machine" must expel some energy in order to expel the entropy that has been created (if it doesn't expel the entropy, the machine doesn't run).  So every time a machine does something, it MUST lose some energy, and it cannot run forever.

Induction changes the kinetic energy of shaking into electrical energy.  The electicity is stored in a capacitor (acting as a short term battery), which feeds into a LED.\n\nPS: friction is not necessary, in fact the less friction the better.

Of course energy is transferred  in energy transformation . How heat can be transferred in mechanical energy transformation or chemical energy transformation . There are  different type of energy like mechanical energy , heat energy, chemical energy and nuclear energy .  The Energy transform in  form of  qunta. Minimum energy transferred will be   h f ( frequency) . h is Planck's constant .
