batteries versus capacitors
What are the limitations of a capacitor versus a battery?
Would it be possible to power a small electronic device with a capacitor, like a laptop? What are the pros and cons of a capacitor versus a chemical battery? Any info would be appreciated.
The capacitor would have very limited storage capacity and the voltage starts dropping as the current starts flowing. Even a small battery is much more efficient in this regard compared to a capacitor. Except for the disposal problems of some chemical batteries (which contain mercury or lead for example), a battery is a better option.
