differentiate between electrical energy and sound energy.
Answers
Explanation:
Difference Between Electric power and electrical energy.
The work is done or energy supplied by the source in maintaining the flow of electric current is called electrical energy whereas he time rate at which electric energy is consumed or dissipated by an electrical device is called electric power
It is equal to the product of power and time i.e. E = P × t whereas electric power is equal to the rate of doing work by an energy source i.e. P = W/T
b) Less the power of the electrical device, higher is its electrical resistance.
c) Kilowatt-hour – Commercial unit of electrical energy 1 kWh = 1000 Wh = 1000 J/S x 3600 sec = 3600000 J = 3.6 x106
The work is done or energy supplied by the source in maintaining the flow of electric current is called electrical energy whereas Sound makes particles vibrate is orderly manner, whereas heat vibrations are random and disordered. That's the basic, macrospopic difference.
