Load shedding is mainly done to a store energy for later user b increase electrical energy in the grid c reduce enery losses d none of the above e all of the above?
Answer is "e" all of above.
It store oil, water in dam and gas for future use.
When load shedding occurs grid energy goes increase.
Theft of electricity is controled through this way.

A kitchen blender transforms electrical energy into mechanical energy Why is the amount of mechanical energy produced less than the amount of electrical energy used?
Losses are due to inefficencies of the motor, and friction on moving parts. Read More
Losses are mainly due to electrical resistance. Read More
Electricity does not occur in natural state. It has to be generated by converting one form of energy into electric energy. The electric energy of any machine can be calculated by subtracting the all losses occurring in a machine (electrical, mechanical and magnetic) from total input power or energy. Read More
The sequence of energy transformation from a battery to a lighter is Chemical Energy---->Electrical Energy---->Heat Energy. These transformations do not ensure 100% transfer of energy as there are losses in the process. Read More
You can use a transformer to increase the current. Note that this will also decrease the voltage. The total energy will not increase; it will decrease slightly, due to losses in the transformer. Read More
No. A transformer doesn't source or sink energy, or convert energy from one form to another. The ideal transformer merely changes the parameters of an electrical current, with no effect on energy levels. A non-ideal (real-life) transformer decreases the energy in the electrical circuit, because its losses rob some of the energy and turn it to heat. Read More
Not quite sure what you mean; a current, by definition, is a flow of electric charges. You can convert electrical energy to some other type of energy, and store the ENERGY, which can then be converted back later (there will always be some losses, of course), but it isn't clear what you mean by "store electrical current".

An 'eddy' (not 'eddi'!) current is a current that flows in the magnetic circuit (core) of an electrical machine, due to a voltage induced into that core by a changing magnetic field. Eddy currents cause energy losses in electrical machines. To minimise eddy currents and, therefore, their losses, machines use laminated cores which restrict the paths through which eddy currents can flow. Read More
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as… Read More
The output is electrical energy. However most use a heat source (e.g. coal, oil, nuclear) to make steam (heat energy) which drives turbines (kinetic energy) the turn alternators (electric energy). At each conversion some energy is wasted to losses. A 1000 MWatt (electrical) power plant may need as much as 1500 MWatts (thermal) to operate. Much of this waste heat goes up the cooling towers. Read More
What is the relationship between energy input energy output and energy losses whenever transfer of energy takes place?
Energy input = energy output + losses. Both energy output and losses are usually positive (they might also be zero in some specific cases), meaning that (usually) each of them individually is less than the energy input. Read More

Iron losses occur due to nature of material this is of two types 1.eddy currents(circulating currents) 2.hystersis loss(nature of material) Copper losses are due to amount of current flowing (given by I2R) Answer Copper losses are energy losses that occur in the primary and secondary windings, whereas iron losses are energy losses that occur in the core.

As far as the load is concerned, they don't. But, as far as the supply lines are concerned, they have to cater for an increase in load current and, therefore, increased line losses, if the reactive power of the load increases. Read More
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy. Read More
No, the purpose of laminating the core is to reduce eddy-current losses. Read More
The reason why amachine cant be one hundred percent effective is as a result of losses.For Electrical machine such as alternator we have Mechanical losses(such as windage and frictional losses)and Electrical losses(such as copper loss in the rotor winding and stator winding).In Mechanical machine the main losses are windage and frictional losses.NOTE;ALL THIS LOSSES RESULT IN THE PRODUCTION OF HEAT,THUS REDUCING THE EFFICIENCY OF THE MACHINE.

One gallon of power is approximately 8.3 pounds, so the energy released, when 1 gallon of water falls 10 feet, is 83 foot-pounds, which is equal to 0.31 watt-hrs. If this energy were mechanically converted to electrical energy, approximately 40% losses would occur in converting the falling water into rotational, mechanical energy by a Pelton wheel or other water impeller, and about a 5% loss in conversion of rotational energy to electrical energy by a… Read More
Losses due to loading. As more load (more current) is put on a transformer, these losses will increase. They are often referred to as I2R (or I^2*R) losses. Read More

Therma losses are heat losses, or losses of heat energy. Just one example is the idea of thermal loss through windows in a structure. Walls can be insulated, but heat energy can pass readily through ordinary window glass. On a cold day, there are a lot of thermal losses from a structure through regular glass windows. Read More
What is the scientific and economic advantage of alternating current for the transmission of electrical energy?
the easiest way to generate large currents is to use the alternators which generates alternate current, generating direct current requires some sort of batteries or cells which are not practical for generating high currents and also have a high cost. Beside, transporting electrical energy through long transmission lines is subject to enormous losses due to the resistivity of electrical wires, so, we have to transmit the energy using high voltages to reduce these losses. high… Read More

If energy is transformed from one form to another, for example electric power to mechanical power in an electric motor, in an ideal situation there would be no losses and therefore an exact equivalent in the new form of energy. In practice there are always losses, the process is not 100 percent efficient. In the above case there will be some thermal losses due to heating in the motor windings, and some windage losses due… Read More
Can an electric motor run a generator to power itself if the motor has a larger gear and the generator has a smaller gear?
Claims about perpetual motion machines are always false because they ignore the inevitable losses of energy which must be overcome to make any machine operate so that it can do its intended work. Such losses mean that any machine, whether electrical or mechanical, must be supplied with more input power than it can convert into output power. In the case of electrical machines there are many reasons for energy losses: Bearing friction losses; "windage" losses… Read More
