electricity energy saving

Electric charges and current attract or repel each other, i.e., they exert forces on each other. Thus, work needs to be done in order to move them with respect to one other. The energy associated with this work is called electrical or electromagnetic energy...

Commercial Unit of Electrical Energy - Kilowatt - hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy ..

Kilowatt - hour is the commercial unit of electrical energy. We have seen that power is the rate of energy consumed or delivered. If 1 joule of energy is used per second, we say that energy is used at the rate of 1 wat..

Commercial Unit of Electrical Energy - The unit 'watt' is very small. Therefore, in actual practice we use a much larger unit called 'kilowatt'. It is equal to 1000 watts. Since electrical energy is the product of power and time, watt hour (W h) can also be c..

The unit 'watt' is very small. Therefore, in actual practice we use a much larger unit called 'kilowatt'. It is equal to 1000 watts. Since electrical energy is the product of power and time, watt hour (W h) can also be considered as unit of electric energy...

The electric potential energy of the alpha particle at the distance of closest approach from the nucleus was found to be equal to Potential energy x charge on a partic..

Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon de..

The energy of flowing water is utilised to produce electricity on a large scale at hydroelectric power plants. This is another conventional source of energy derived from flowing water. Dams are constructed across the waterfalls to derive electrical ener..

In the case of electrochemical cells, free energy change, D G is related to the electrical work done in the cell. If E is the e.m.f of the cell and n mole of electrons are involved, the electrical work done will be D G = -nFE c e l l , where F is Faraday constant..
