what is the difference between capacitor and battery ?

2 Answers

1) Capacitor is an electrostatic device where as Battrey is an electrochemical device
2) Capacitors can be polarized or non polarized but battreys are always polarized
3) The charging rate and discharging rate of Capacitor is faster than a battrey

A capacitor stores power but in very small quantitys  and work in D/C and A/C circuits and it needs a power source from wich it gets the power it stores and a battery also stores power  but in much larger quantitys measured in Amp/Hours
