If 'i' amperes of current is established in a coil in time 'dt', then 'dw' amount of work done if 'e' stands for the induced e.m.f. dw = - e I..

Sunlight falling on the earth's surface equals 50,000 times the energy used each year by man. Almost all our energy comes from sun. The sun's energy is responsible for the tidal energy, heat energy stored in water, the chemical energy st..

>In a hydro power plant electricity is produced from water. Hydro power plants convert the potential energy of falling water into electricity. Wind Energy Moving air is called wind Wind possesses kinetic energy Wind energy c..

Advantages of Using Solar Energy - It is present everywhere. It is available in plenty. It does not cause any environmental pollution like the fossil fuels and nuclear power. Solar cells last a longer time and have low running costs. In the first half of the twentieth ..

In an electrical circuit, energy is supplied by the source of EMF, stored by the capacitive and inductive elements and dissipated in resistive element..

In an electrical circuit, energy is supplied by the source of EMF, stored by the capacitive and inductive elements and dissipated in resistive elements. Conservation of energy requires that, at any particular time, the rate at which energy is supplied by the source of ..

Non-renewable or conventional energy resources. Most of the energy, which people are using, is derived directly or indirectly from the sun. Non-renewable energy resources are those, which have been in use since a long time. Availability of petroleum is limited. Petro..

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy gets depleted over a certain peri..

The above resources can be classified as renewable or non-renewable. Some resources are constantly produced on the earth and are known as renewable resources. Others are not replenished and are called non-renewable sources. Resources Renewable resources Non-renewable resources Solar power..

Neutrons and protons attract each other at distances of order of 10 - 1 5 m, and bind (come together) to form nuclei. The associated energy is called nuclear energy. For example, because of this attraction, a helium nucleus (consisting of two protons and two neutron..
