It isn't "the best"; it is useful for some specific purposes.
Electrial energy
we used pawan chakki to transformed its electrial energy
heat energy is converted into electrial enegry when passed from magnetic energy
True. Light is a form of electromagnetic energy.
transformer
That could be a power cell (battery), or more correctly, a capacitor.
by switching off the electrial items in the absence of any person
there will be no internet and things that are made of electrial would not work.
No, nothing like that. It is less than 20 percent
Move a magnet near a conductor of electricity faster. Strike a piezoelectric crystal.
Ordinary light bulbs, fluorescent tubes, CFLs, flashlight bulbs, LEDs, toaster elements, and laser diodes all do that.
electrical energy gives and provides energy to give energy and to show energy, light energy goes through a system of energy and gives off energy to provides it. heat energy is like sunlight it gives, take , provides, and uses energy.
