As energy is the capacity to do work, power can also be defined as energy consumed in unit tim..

Imagine two students positioned at track A and track B of 100 m length shifting 10 bricks from one end of the track to the other end. What is the amount of work done by each one of them? The amount of work done is same but the time taken to perform the work varies. In order to find out the fastest ..

Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric power consumed P..

1D If there is convex lens of power 1 D then its focal length is equal 1 metre. The power of a convex lens is positive and concave lens is negative. If the focal lengths of the individual lenses f 1 f 2 are f 1 , f 2 ....... then the focal length of the equivalent lens is given ..

Whenever a ray of light passes through a lens (except when it passes through the optical centre) it bend..

Thermal Power Plant (Thermal Energy) - Large amount of fossil fuels are burnt everyday in power stations to heat up water, to produce steam which further runs the turbines to generate electricity. The transmission of electricity is more efficient than transporting coal or petrol..

Large amount of fossil fuels are burnt everyday in power stations to heat up water, to produce steam which further runs the turbines to generate electricity. The transmission of electricity is more efficient than transporting coal or petroleum over the same distance. Therefore, many ..

Kilowatt and megawatt are higher units of power. Another unit of power is horse power 1 horse power = 746 wat..

Hydro-electric Power Plant (Hydro-electric Energy) - 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 waterfall..
